It would have to be the Predator X11
I know guys who run the BJ & Yok and both seem very good. The Yokomo looks very nice to me, just suffers from the same as all belt drive, i.e. slipping belts & sh*t in the pulleys. But all cars need maintenance of some sort.
I can't comment on the Tamiya - but isn't it very similar to the Yokomo?
Personally I'm a fan of shaft drive all the way, but on the track there's nothing in it to be fair.
They are all good kits.
