Shiamano center lock rotors seem much better than sram. Adapters are trash.
if using multiples wheels 6 bolt is nice because you can buy shims to get spacing the same. I am guessing the same can be done with center lock but I have never seen them. I use 6 bolt because I have sram rotors and have spaced rotors on all bikes the same.
if you only will have one wheel set and can get a nice shimano or dt Swiss hub and use high quality shimano rotors center lock will be great.
