I tend to forget the 32bit versions of Vista and Win7 exist. There isn't really any reason to use them. The 64bit versions are only likely to run into extra compatibility issues with very old programs that need to integrate themselves with pretty low-level system functions. So, no 15 year old hardware drivers. That sort of thing isn't really a concern for most people though. I think XP64 had some nasty compatibility issues, but it's not like it was really intended for mainstream users.
