Team 118 with their motor assisted human feeder has my vote as the finest cycler. Even though they didn't go all the way in Galileo, they played exceptionally well during their final matches:

Of course, they weren't just a pure cycler, as they had a ground intake, but the same can be said of many of the best cyclers. Asking for robots that could only cycle involves, ironically, taking out so many of the very best cyclers . . . this question is too hard!
Team 126 has my vote, they are blazing quick and use mecanums to great effect. Team 868 is also stunning, but somebody seems to have revealed their hidden FCS tendencies
