I retired from Sikorky 2.5 years ago so I was familiar with the X2 demonstrator (chief pilot was a friend of mine) that led to the Raider. The Raider is still in the demonstrator stage so quite a ways to go before it goes into production. I do not have much info on it. As far as the JMR is concerned , that happened after I left so I am in the same boat as you as far as being knowledgeable about it.
Here is my post from another forum repeated here(with some additional info I just added):
They are different, most notably with regards to the mission system. (The airframes are both made by Sikorsky). The S-70B was designed for the international market place. It was designed to be easily modified and tailored for each customer. This is due to the fact that most, if not all, international customers will want to integrate capabilities or equipment not current available on an existing configuration of that aircraft and Sikorsky has substantial experience in doing this. The MH-60R was designed for the US navy. The system has to be "dumbed down" (restricted equipment must be removed) to create an exportable version and then new capabilities or equipment integrated. This is a much more difficult and labor intensive task. The MH-60R is employs a single operator to handle both tactical and accoustic functions in the rear of the aircraft. This "integrated sonics" approach offers some advantages including requiring one less crew member but it does not meet the criteria for dual operators for the Indian navy. The MH-60R does not have an anti ship missile integrated other than the Hellfire (The S-70B has the Penguin). 60R uses the FLASH sonar, S-70B uses the HELRAS sonar (I believe the FLASH will be integrated for India). The mission system operator interface and overall design (Done by Lockheed Martin) has been criticized by operators and pilots as not being very user friendly and other info indicates on going problems with the system. An upgrade is in the works including adding a track ball to enhance operator interaction with the system but in initial testing this has received only luke warm reviews by the crews. The S-70B uses a Multi-Slew Controller (MSC) which is awesome in allowing the operators to graphically interact with the mission system. The S-70B mission system is a Sikorsky and Rockwell Collins design that is now in its 5th generation. It is, in my opinion, the best in mission systems out there. It has been continually updated over the years to add new capabilities and address obsolescence issues. The new Automatic Flight Control System (AFCS) & Weapons Management System (WMS) are examples that offer outstanding capabilities. The MK-54 torpedo (which India is getting as part of tis P-8 patrol aircraft purchase) has already been fully integrated.
Lockheed Martin is working on a "Green" export version of the MH-60R that I believe will offered for the next tender. The 60R was not chosen for this tender because it was only offered via the Foreign Military Sales (FMS) procedure which India did not want. I expect that it will be offered as Direct Commercial Sale in the next tender. But, I believe it will prove almost impossible to overcome the S-70B momentum assuming Sikorsky does its usual good job and India is happy with the aircraft they receive. Turkey, Singapore, & Brazil have all placed follow-on orders for the 70B so that should say something about their satisfaction with the aircraft.
