Pros and cons of MIT Scheme and DrScheme for studying SICP

Question

What are the pros and cons of using MIT Scheme versus using DrScheme, in the context of trying to go through SICP (presumably simultaneously to watching some / all the MIT 6.001 videos)?

Answer 1

I switched from MIT Scheme to DrScheme specifically because I couldn't get a version of MIT that runs on 64-bit Windows. I run DrScheme with the Language "Module" selected to do the SICP exercises.
