smallest code usually Watcom, gcc similar, Turbo ~15% larger.

however UPX compresses Turbo code better, so often the binary is smaller.

of course this depends a lot on

a) the amount of runtime library pulled in by your code
b) the memory model
c) CPU type
d) calling conventions
e) the kind of code that you wrote (watcom optimizer optimizes much better then turbo)

so you have to do your own experiments.
