Answers like this annoy me. If someone asks "What is better, a Dollar Store Brand, or a Zhanchi?" Well, I could say that it is personal preference. I understand that some cubes are so good, that it does come down to person preference. But you could at least say "Cube a is smooth, while cube b is crispy. Cube a is slightly faster than cube b, and both cube have equal corner cutting, etc." or just not answer. Most people realize that these cubes come down to personal preference, so you could at least compare them.
Note: methods that normally require a lot of inspection time are at a disadvantage as you kinda jump straight into the 3x3 stage. So I'd imagine ZZ is tricky.
For fewest moves, do cube rotations count as a move? According to this regulation: E1a) The maximum length of a solution is 80 (moves and rotations), rotations should count as a move but then I've also seen somewhere in this forum that cube rotations do not count as a move.
