As far as how much I enjoy them? It's basically the order they came out - Fusion > Synchro > XYZ > Link - Aside from Pendulum, each one is basically a power crept/simplified/dumbed down version of what came before (Fusion requiring specific monsters, synchro requiring a tuner + level match, xyz just requiring a level match, link not having any specific requirements beyond warm bodies for the most part)

Pendulum is hard to rank, because the idea of play monster into S&T Zone -> Get some effect + goes to extra deck on destruction -> Can summon from there on some condition (Basically, the idea of them as extra deck cards) is actually quite cool. However, the Pendulum Summoning mechanic is generally really dumb even if it might be the only way to get some of those cards out of your extra deck.
