What are your thoughts - which is the best class right now?

I don't have all that much time to play, but I've managed to try all six classes a tiny bit over this weekend.

My initial feeling is that ranger classes ( merc, ranger, witch, sorceress ) seem much easier to play than melee classes ( warrior and monk ). Monk's combo system looked awesome, but for a casual and lazy bastard like me, it looked like way too much effort to manage effectively. And the fact that a bunch of weapons are still missing from the game, and Warrior was pretty much limited to using maces and mace skills only, made Warrior kind of lacklustre for me. His skills seemed all delayed, and managing those delays seemed such an effort that I lost interest in the class.

Witch, seemed awesome, both as minion manager, but I also really liked that with skills like unearth and firewall you don't really need to build a minion witch - you get minions anyway, which seemed nice.
Merc felt unique - the shotgun type of gameplay worked very well, but also, it seemed that the grenades were so much better than anything else, and other mercs who did not play with grenades were struggling on lower levels.
Ranger is the typical cookie-cutter ranger champ. There is nothing special there, but it is still very playable and enjoyable.
Sorcerer - same as a ranger. It's nothing special, but it's very nice to play.

So what are your thoughts? Which is the strongest class right now? Which is easiest to play? Which is the best for you?
