Best monster variation?

What do you think the best variation of monster card is? Fusion, Ritual, Synchro, or XYZ?

In my opinion XYZ are the best. They're the easiest to bring out, and make the most dynamic use of the game. Rituals are by far the worst because you have to draw two specific cards to summon, and usually they're just not worth it.

XYZ are good, but I'm going to say it the synchros that are the best simply because of their summoning speed. You can easily get 3 synchro summons in one turn without much effort. That really stacks the odds in your favor fast in a duel.

I would say t would go like this (from best to worst)

XYZ
Synchro
Fusion
Ritual

I'm actually going to lean toward Fusions because while they take a little more work to bring out, they pack a bigger punch. I'm even thinking of bringing the roids back from the dead.
