Type 055 have very good hull design and sensor package. The hull design is informed by RCS reduction shaping considerations from the get-go. The hull design and modular VLS design - both provide much room for important updates to Type 055 in the years to come. Credit where due.
Ticonderoga-class hull design looks dated but its sheer size provided much room for important updates to keep up with emerging threats; the Aegis Combat System was something new and a big leap from contemporary warship systems in the 1970s, and its EVOLUTION continued:
"The Aegis system has a federated architecture with four subsystems – the AN/SPY-1 multifunction radar, the command and decision system (CDS), Aegis display system (ADS) and the weapon control system (WCS).
Aegis Baseline 7.1 is based on COTS (commercial-off-the-shelf) computer architecture and includes a new AN/SPY-1D(V) radar with enhanced electronic countermeasures and more effective capability in littoral environments.
Baseline 7.1 was certified by the USN in September 2005 on board Arleigh Burke destroyer USS Pinkney (DDG 91). In December 2007, the USN approved the latest Aegis upgrade Aegis Open Architecture. Work on the vessel began in February 2008 under the US Navy’s cruiser modernisation programme (CMP). USS Bunker Hill (CG 52) was the first vessel to be equipped with the Lockheed Martin’s open architecture Aegis Weapon system in 2008 and underwent operational trials of its full combat system in 2009. All 22 Ticonderoga cruisers were fitted with Aegis Open Architecture by 2018."

Ticonderoga-class is well-equipped to tackle
a wide range of modern threats with latest
munitions and
EW capabilities. The much EVOLVED Aegis Combat System makes it possible for the host warship to detect and engage ELUSIVE threats from a distance:
Such live-intercepts are
not possible with outdated federated sensor systems in use. You can expect this level of sensor fidelity from an advanced AESA solution. AESA is a leap from PESA in theory no doubt but baseline architecture(s) can be amended and/or transformed with circuit modifications and introducing new algorithms in the mix; these developments are kept under wraps due to obvious reasons. Therefore, it might not be practical to compare sensor architecture of both warships in black-and-white manner. Some of the Ticonderoga-class have the latest
BASELINE 9 configuration in fact; modernization efforts continue as WE speak.
See above.
Type 055 have very good sensor package but mission capability is contingent munitions and EW capabilities by and large. Type 055 is equipped with offensive munitions such as YJ-83 ASCM and YJ-18 ASCM respectively. YJ-18 ASCM (range = 290 NM) makes it possible for the host warship to engage other warships from considerable distance(s). Defensive options are HHQ-10 (similar to RIM-116), HHQ-16 (derivative of SA-17), and
HHQ-9B (derivative S-400); this payload is impressive in theory but performance levels are similar to Patriots and higher number of missiles might be expended to engage incoming missiles subject to varying complexity levels. Therefore, Type 055 should be in the position to attack FIRST which was possible with YJ-18 ASCAM.
Ticonderoga-class is very good in the defensive regime due to much EVOLVED Aegis Combat System and vastly superior munitions (SM-3; SM-6; SM-2 Block 4; sophisticated decoys) - primary advantage of Type 055 blunted by extension.
Offensive options of Ticonderoga-class are modernized Harpoon (SLAM-ER; range = 155 NM) and SM-6 (range = classified) respectively. However, it is possible that some of the Tomahawks are optimized for anti-ship engagements (element of surprise).
Therefore, Ticonderoga-class is well-equipped to engage another warship in theory. This might not even be necessary in the presence of an aircraft carrier however. And when two or more warships of USN are involved in a mission, they are more effective and resilient due to
CEC.
You were corrected in this regard before.
"Due to cost reasons, so far only the Zumwalt class destroyer DDG-1000 [3] is a true RF stealth vessel, its radar cross section (RCS) is reported to be -34 dB less than that of the Arleigh Burke class destroyer in X band, however its production number is limited to only 3 due to its prohibitive high cost, and US Navy is building a large number of Littoral Combat Ship (LCS) [4] to make up the shortage in fleet number."

AMDR is a revolutionary RMA architecture and its sensor fidelity is twice that of already very impressive AN/SPY-1D(v). Type 349A being double-band is not sufficient to infer similarity with AMDR.
See above.
The Zumwalt class is
not a failure.
1. The Americans stress-tested the Zumwalt class destroyers in rough environments and they passed with flying colors.
"The stealth destroyer Zumwalt aced its rough seas testing, leaders from Naval Sea Systems Command said in a recent release.
Engineers from the Naval Surface Warfare Centers Carderock Division and Philadelphia Division carried out tests late last year on Zumwalt as part of the ship’s Performance and Special Trials, which are conducted on the lead ship of every class to test how the ship behaves in various sea conditions.
The ship held its own through the high end of Sea State 6, which means 20-foot seas, according to a Naval Sea Systems Command press release, with ship and crew performing at acceptable levels according to the parameters of the test.
“There were no exceedances of critical motion criteria limits,” the release read.
The test results confirmed what the ship’s commanding officer told Defense News last January: That Zumwalt’s tumblehome hull design performed well in heavy seas, meaning the tumblehome hull could be viable for future classes of a surface combatant."

2. The Zumwalt class destroyers will receive a new generation of munitions, and will be particularly armed for long-distance anti-ship missions.

And following:
These destroyers will be increasingly relevant in the near future.
Type 055 is an impressive achievement for the Chinese (I am a fan as well), but it is a matter of conventional wisdom to have realistic views and expectations.
The Zumwalt class is a true LO-compliant warship design with unparalleled levels of automation and capacity to endure harsh maritime conditions.
Global advances in sensor systems are expanded upon in scientific studies. Modern Full Digital Phased Array Radar systems were conceived years ago.

Leveraging years of experience, the Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU) is building the first-ever, mobile polarimetric, all-digital phased array radar (PAR),1 as depicted in Figure 1. As technology has significantly evolved over the last 10 to 15 years...

Revolutionary architecture such as that of AMDR is not an easy accomplishment and happens once in a while.
