Some people feel more comfortable with older compilers they have
used and tested extensively for their applications.  If one or
the other works better for someone, they are encouraged to use
that one.  :)

Generally speaking, there shouldn't be any major differences....

Yes, one should be able to mix and match C binaries and object
files.  Don't try to mix C++ from the different compiler versions
however, as it won't work.
