This depends on a few things for me, I like to replay a good game, but for a DnD game there are a few things to consider, what I want to play is going to deal with a lot of other factors in the game.
At the current state of the game, I have to consider party balance, level cap, starting stats and just how much I like the class, I have played all. Right now I throw out being a wizard because I like Gale, and there is no fireball. Spellcasting without the ability fireball a gazeebo just doesnt feel right. Also I will play it because the class doesnt rely on really needing good numbers in too many stats and so I can have a decent int and con and maybe throw a higher number into charisma enough to not have to pay so much for goods (I really hate the ignoring of cost in this game)
If we get to roll stats at some point I would like to play any of the classes that have needs for multiple stats. Paladins are fun but they need the melee classes, charisma, and traditionally some wisdom (yeah I know they dont need it any more but seeing a Paladin with the 10 in wisdom is disappointing to make). Also Barbarians in games like this are fun if you have stats high enough, if you roll a barbarian with three high stats (or can min max to them with the pregenerated numbers) I always find it fun to go unarmored with high con and dex and just run into battle naked, in all your natural glory ;P The same for monks but robed. With the current standard stats the classes dont seem to call to my power gamer side the way theyve done in the past
I also do like playing rogues but right now party balance keeps me from it, as I prefer the rogue npc over the other characters but two rogues may not make for proper balance. If full release gives us some more tolerable NPC characters to chose from then maybe.
