Yes, there aren't many extremely fast people who use ZZ for OH and CFOP for 2H. If you're talking about different LL methods, or partial COL, there are some people who do that. I personally use a slightly different LL method, basically if I have an OLL I don't know, I do the first step of 2 look OLL, except I also permute the corners (in one alg), so the cube can be solved entirely 2 gen. Plus, if you only know a few algs, you have a 1/12 chance of a PLL skip. Then for the F2L pairs on the left, I will sometimes put the cross on the left.
If you're just starting out, use the exact same method though.
