Not sure about technology, but in term of money put into it and in term of numbers, China is still far behind US. And one need to be a blinded, ignorant fool to think otherwise.
Number
While China indeed building ahead of US, but it was not by much, China commissioned 9 Capital Ship during 2019.
1x Type 002 Air Craft Carrier
1x Type 075
1x Type 071
5x Type 052D Destroyer
1x Type 055 Destroyer
US however, have commissioned 6 ships
1 x Ford Class Carrier
1 x America Class LHA
1 x Zumwalt Class Destroyer
3 x Arleigh Burke class Destroyer
However, the number favour US because even though they launched 6 ships in 2019, they already outnumber current Chinese ship. At the current commission rate. China would have to wait until
32+ years to be in parity with US Carrier number (China launch 1 carrier every 3 years)
20+ years to be in parity with US Amphibious Assault Ship
16 years to be in parity with US Cruiser
18 years to be in parity with US Destroyer.
On the other hand, US is also ahead of newly commissioned by tonnage. (1 Ford Class Carrier alone already equal to the tonnage of all the destroyer commissioned by the Chinese)
Money
US defence budget is 690 billions, account of GAO office, 46% of its budget goes to US Navy. Which mean US Navy budget is roughly 300 billions. On the other hand, Chinese Defence Budget is roughly 200 billions. Yes, in Purchase Power term, Chinese budget would have around 320 billions (to USD) but that is the whole budget, which mean in reality, Chinese Navy budget is highly likely smaller than the US Navy even after factor in purchase power.
Bases
Bases is important as they are to service the ship, ship require regular service so the number of base dictate how many ship a navy can put into the sea. Also indirectly affect the number of ship a country can have.
China have 16 major Naval Base (with 15 minor base) along its coastline. They are
Qingdao, Huludao, Jianggezhuang, Guzhen Bay, Lushun, Xiaopingdao, Ningbo (HQ), Zhoushan, Shanghai, Daxie, Fujian, Zhanjiang (HQ), Yulin, Huangfu, Hong Kong, Guangzhou.
Which service 3 fleet, Eastern Fleet, Southern Fleet and Northern Fleet
US, on the other hand, have 48 major Naval base inside and outside of CONUS (and 21 minor structure). Plus, US can have access to all NATO partner base, which further expand the basing structure to almost 70.

US have 6 active Fleet, 1 reserve Fleet
With this matrix, apart from some serious technological gap between China and US, we can deduce that US Navy is still ahead (Quite ahead actually) in term of number, money and bases. I will say China is catching up go the US Pacific Fleet power soon (Which encompass 3 US naval fleet, 3rd, 5th and 7th) but I doubt China can overtake US navy power as a whole.
Technology wise, I think the debate is a moot point, because to have any meaningful debate, one need to know both Navy inside and out, I don't think such person exist, so it come down to each side speak on behalf of their own side, which basically turn into a you said, I said kind of argument, which again, is a moot point.
