I'm going to say 254/60/968 and the West Coast Drive (6WD) is the best all-around drive (i.e., does everything well). 118's coaxial swerves are probably the best in the "standard" 4-wheel swerve. Plenty of pictures of 254/60/968 on CD-Media (visible under the hopper in http://www.chiefdelphi.com/media/photos/23573, http://www.chiefdelphi.com/media/photos/26141, http://www.chiefdelphi.com/media/photos/27537). 118's swerves are better seen in the Behind the Design books, but the one from 2007 is at http://www.chiefdelphi.com/media/photos/27221, though poorly visible.

The transmission from 254/968 in 2007 (http://www.chiefdelphi.com/media/photos/27018, http://www.chiefdelphi.com/media/photos/28070) is one of the best 2-speed trannies in FRC, but it's tough to make (and AM sells plenty of 2-speed trannies). It weighs just over 1 lb without the motors, and their robot was plenty good to go with it.
