Why? EoCross = Xcross/Cross+1, same movecount, 9 ZZ 3 pairs>CFOP 3 pairs, no cube rotations, all RUL ZZ last pair>OLL, you can sub-0.6 last pair ZBLL=PLL, PLL is ZBLL anyway. 2 steps are better, the others are equal. ZZ is better.
in my opinion it is much harder to look ahead and RUL is not the best finger tricks. IMO RULF with very few Ls is better.
