    Besides the obvious 32 bits? Well, if your operating system supports 64, and that is most of them,  bits then use the 64 bit version.  Some older OSes are 32 bit and you should use the 32 bit variant. 

    Rule of thumb -- if your OS and hardware are not over five years old you should probably be using the 64 bit version.

    I don't get it, what do you mean by the "obvious 32 bits?" , I am using a 64-bit OS but also a 32-bit application can run on it, I mean is there a really differences in performance of the MySQL itself not on the limit by the OS of being 32-bit
