By what we used:

VexPro Traction Wheels plus hubs and sprockets: These were great. Once I managed to explain the assembly order to my drivetrain mentor they went together in a breeze. I think the excellent piloting and sprocket alignment is the reason we hardly ever had to work on chain tension during the season.

Ball-shifters: We didn't have any problems dropping output shafts. The assembly turned a little tricky when my mentors decided to completely disassemble the things to see how they worked, but that's not a mark against the gearbox. The only trouble we had was with the encoder output solution. The press-fit between the output shaft, encoder gear, and bearing wasn't quite tight enough to be 100% no-slip. Our solution was a dab of threadlocker. I can't actually say how it worked because we never got the encoders tied into the control system, but it seemed likely to work.

Versaplanetaries: Great gearbox or greatest gearbox? Either way they're awesome. The ease of playing with multiple ratios made developing systems much faster. And I got to personally thank JVN at Lone Star when a topple took out one of our shooter motors and we had it replaced and running for the next match after a timeout. We would've been completely hosed if that happened with a P60 gearbox.
