Yep that is true. Also V and N perms aren't that much slower. Just learn good algs and fingertricks.
Very true. I think for beginners they are notably slower, but IMO getting those to 2 or 1.5 isn't hard if you have the right algs and solid fingertricks.
Sune and antisune is widely considered worst and not worth it but some learn.
There is a notable difference between "not worth it" and "worst". Most people have 0 experience* with Sune or Antisune ZBLL, but for some reason they give advice all the time. In my experience, and what I've heard from other people who have learned more Sune ZBLL than I have, is that it is a good set, but it is not worth it for a couple reasons.
OCLL prediction from LS with CP recog during sune execution (~.4) can lead to a 1.5 second LL pretty easily, assuming you have your PLLs sub 1. This is why people who have learned Sune ZBLL don't recommend learning it, not because it's a bad set, but because it's not worth it since the alternatives as already fast enough.
(and IMO H is the worst set, although there might be some bias present because it's
my worst set as my recognition is still crap)
Start with the T or U set and move on to L after learning T and U. Then decide to go for Pi and H or the sunes if you atucally want to know full ZBLL rather than a good chunk.
Yep, TUL is a good group to learn/start with/stick with. Not too many bad cases/algs and pretty well developed.
*As a disclaimer, I don't know full Sune yet. I do know about 35% of Sune/Anti Sune ZBLL. I
have selected all my algs though, so I have tried every case and every alg, but I haven't memorized them or the recognition for most of the cases yet. They're good algs.
