I think the debate on the BB transmissions has been settled... in favour of Banebots.

Comments on the BB transmission reliability comes from the initial batch of gearboxes that were shipped in the KOP two years ago. Through an effort between teams, FIRST and Banebots the reliability issue was identified as an insufficiently hardened final stage carrier plate. Banebots took responsbility for the problem and issued every FRC team replacement, properly hardened, carrier plates, and then took additional steps to toughen their gearboxes.

As far as I know, teams using the new carrier plates and/or new transmissions have had no issues with the BB transmissions.

The BB transmissions are ideal for omni-drive drivetrains as they are extremely easy to use in direct drive (as opposed to chain drive) applications. You just put the wheel on the output shaft, saving all the weight of the chain and sprockets, as well as the potential failure of having the chain come off. In my experience, the upgraded Banebots make for the most reliable drive system out there.... and we've got a mecanum drive with four of the 12:1 gearboxes on board with two regionals and several demonstrations behind them to back it up with.
