Which is the best among Visual Prolog, SWI-Prolog, and others?

Question

I have searched the Internet and stackoverflow.com, but got nothing.

Who can give me a comparison between various Prolog compilers/IDEs such as Visual Prolog and SWI-Pro

Answer 1

I'd recommend Amzil Prolog because of it's GREAT Eclipse IDE Plugin. You'll find it here: Official Site.
