6 Bolt versus Shimano CenterLok. The Shimano uses the tool that’s the same as the cassette lockring. CenterLok is possibly more popular on road disc wheels, 6 bolt is common on mt bike. Both work equally well, though 6 bolt you want to occasionally check bolt tightness. I have 2 sets of wheels for my gravel bike, one is 6 bolt, one is Centerlok, I can swap with no adjustments needed.
