Trust me, you won't feel any difference in speed when comparing bearings. With that being said, Reds are better imo because of the durability. I've had my set for 4 years now, and haven't cleaned them once. They still roll like it came out right out of the box though!
Seismic tekton are my favorite they got the built in spacers, last forever on my fun slide board and got the ceramics with bear precisions on my Evo but that's me and mine. Reds are good keep em clean and have fun
