Research Fellowship - Please help!

Hello everyone, I am an IMG with low scores (Step 1: 212, CK: 222, CS: pass, Step 3: 199) all on first attempt. I have 5 USCE (University of Miami, Northwestern and Cleveland Clinic FL) and received 5 LORs. Had 5 interviews for Internal Medicine, but did not match this cycle. Now, I have been accepted in 2 different research fellowships and I have to decide between those two. One is in Mass General (Harvard) with the founder of the arrhythmia service in Harvard (I want to be a Cardiologist),... Research Fellowship - Please help!
