Excluding the two super-dominant 71 machines, you could argue for:
- 1114's 2008 Robot
- 254's 2014 Robot
- 469's 2010 Robot
I think that's really all I can think of for dominant robots in the modern age of FIRST.
I recall having a discussion with a friend about which robot was more impressive, 254 in 2014 or 1114 in 2008. We concluded that while both were phenomenal, the fact that 254 managed to not only dominate, but do so in Aerial Assist, an extremely hard game to dominate, given the nature of the game to rely on alliance partners and such.
