DMT for sure.
I have EzeLap for long time because they only offer full furface 11.5"X2.5" bench stones, but DMT starts making same bench stones, I got one to try and now using only DMT especially 120 grit which is quite a steel eater. May be because of monocrystalline but it sharpen much more aggressive.
For example new 325 grit DMT outperform new 150 grit EzeLap! Only consern I have with DMT - surface of superfine stone not as flat as I like to see, may be it will wear out but EzeLap 1200 much more accurate. I am not sure will some use in time fix it but for now in certain place I have edge scratched by some micro bumps on DMT.
Thanks, Vassili.
