Back in the 8-bit/16-bit days: EGM and Gamepro (honorable mention to NP, it only focused on one System)
Afterwards: OPM (again the same as NP, but there were really only two main disc based systems, plus you got a Free Disc full of Demos before the Streaming/DL era)
Overall I think I liked EGM, esp because of their pretty much honest Reviewers
