I have both for my mill, ceramic and bearing, so I've ran them both quite a bit and heat has never been a problem for me, for either one...From things I have read, and they would most likely stay way cooler.. You disagree?
I don't think bearings are way better, for me they seem about equal as long as they are properly adjusted. Personally, I think they both work well, but a mill is MUCH quieter with the ceramic guides on it.
Those metal bearing guides transmit a lot of sound.
