I think Albert Einstein-Montefiore does have a reputation for being malignant. The residents work really hard yet come out as excellent clinicians. They are probably not in the same category as Columbia, NYU or Mount Sinai amongst the NY programs.
As compared to U Maryland, Montefiore is probably at least comparable if not better than UMD. UMD's program is supposedly somewhat cush. UVA is probably a step above Montefiore and UMD in terms of reputation.
It also depends on location. If you want to eventually practice medicine in NY, then Montefiore will be your best bet. If you want to live in Maryland, go to Maryland, etc...
