Actually, TY programs are generally regarded as easier (in terms of hours) and more competitive than prelims in medicine or surgery. I assume your question is really about which programs are the cushiest.
The TY programs that I liked in NY were as follows:
1. Mt.Sinai - Cabrini
2. NYMC at St. Vincent's Hospital
I can't remember all the details because it's been a long time since I interviewed. However, I remember both programs offering lots of electives and a very kind call schedule. I also interviewed at the Medicine Prelim at NYU - Downtown Hospital. I ranked the program fairly low, but the pay was much higher than the other programs ($50,000 for PGY-1) and they offered a studio for $100-$200 in the Financial District -- not a terrible deal if you're single!
Just outside of NY, I interviewed at the two TYs affiliated with Yale. I thought both programs were pretty good and the hours were pretty decent. Anyway, that's about it for me since I didn't want to be in NY for internship or residency. Both programs in NY are extremely competitive because you are competing with people going into Derm, Rads, EM, etc. Most of them would rather not do a prelim in medicine or surgery too (at least the smart ones
).
Anyway, most PM&R programs would prefer that you do a prelim in medicine (some even require you to). However, most of the residents in my program opted to do a TY. Unless you like IM or GS, I would highly recommend trying to get into a TY program. As a prelim in medicine or surgery, you pretty much get integrated into the medicine or surgery service. Therefore, you have more responsibilites and more is expected of you (at least that was the way it was in my program). Also, TY programs generally offer more elective time (I had four months) and this translates into no calls during those months. With the elective time, I spent two months doing Pain Management and the Rads Interns spent all four months in the Radiology department. Good luck.
