My bet is on ZZ.
ZZ is not exactly a "method", it just adds an extra step in the beginning.
If you do ZZ F2L like Fridrich, then you're not doing ZZ F2L. If you do it like Petrus, then you're not doing ZZ F2L. The 'ZZ method' also has its own unique LL method. It's called ZZLL.
Please do not make assertions about things you know nothing about!
i know ZZ, ive used it. but i never bothered using the algs for ZZLL
