Well, they all have two things in common, they save some moves and some sets lookahead, Winter variation is a shorter movecount version of OLL, COLL make you always get corners solves PLLs which is really easy. ZBLL saves a lot of moves, like 9 moves on average, but unfortunately, recognition is a lot slower than just OLL and PLL so lookahead didn't win in ZBLL but... that is what I can tell in two handed solving, for one handed solving, most of ZBLL's algs are 2 gen which makes it really easy to perform in OH and that 2 gen thing is common in WV and COLL.
