CFOP: This method is just easier to get fast with mostly because the majority of us used LBL as a beginner method. CFOP is just a faster method of LBL, solving the cross perfectly and instantly and solving the first layer and second layer in one progress. If you're very good with inspection...

Yay. I'm Sub-15ish with Petrus (and a little Lazy CFOP-ish). At least with Petrus, I'm able to solve faster because I turn fast and solve it in quite fewer moves than CFOP. (Roux is just very confusing.) And the fact that I don't need lookahead is just way easier for me. (If you know me, I can't...
