Do you mean works best to compile geany? Or to build your own programs from source that were edited using geany? 
Since the build command is customizable in the "set build commands" menu, I think all should work fine. 
The important distinguishing factor might be linking to libraries perhaps, but if you can compile from command line that should also be easy to set.
Or if you create a Makefile then anything goes!
Which compilers are you considering?
