They're all good. If you don't win on any of those bikes, it's not the bikes fault.
Ride the ones that fit and pick the one that feels the best.
Obviously if you get a club/team deal on one of them, check that brand out first.

While I love my R3SL, the R3 is a bit dated now- standard BB shell instead of bearing inserts of one type or another, non tapered steerer. If you beleive those things make a difference.
