I have one bike with a BBInfinite BB/Shimano HTII crank, one with a Wheels Mfg BB/Shimano HTII crank, one with a FSA BB/FSA crank and multiple with the old school square taper design. The BBInfinite piece is the middle CeramiTech option and the Wheels MFG piece is standard bearings. The Wheels BB spins easier than the standard square taper units but the BBinfinite piece is so much easier than the Wheels piece. Is the BBInfinite overkill for me? Yes but it sure is smooth and easy. I'm waiting for better weather to fully assess the Wheels piece.
