What COLL Subsets are worth learning?

[qwr]

none of them - learn ZBLLs instead (or so I've heard)

 

[Thom S.]

J perm said that most of COLL is not worth it if you use CFOP and you shouldn't even consider learning Sune and Anti-Sune because they are so fast and other cases, like half of Pi have easy enough recognition but the algs are slow and you can just predict the ROLL instead.

A few years prior to that video you are referencing J Perm also said that COLL is worth learning even for CFOP users, because EPLLs are super fast, you get PLL skips all the time, the algs aren't much slower than the OCLLs and recognition is easy. Then he made a Playlist about most of COLL
So what's your argument?

How do you recog them? I think I might actually learn them.

I always(because I don't care about speed enough to recognise them from every angle) so the yellow top piece is facing UFL for sune and UFR for AS.
Then look at the other sticker you can see. That is your reference.
Search for the top sticker that is the opposite to your colour. Every possibility narrows it down to two cases.
Then look at RUF(or LUF) and see if that sticker is opposite or same to the reference.
Three sticker recognition.
There is also a method where you only look at the top and then one side sticker but I found mine easier.
