My favorite would have to be Siegfried, he's my only character actually. I think his fighting style is great and easy to adapt to.
His looks are just cool, though SC IV's Soul Calibur shouldn't be such a bizarre sword. I always used the one from SC III.
His personality is one of my favorites too, he isn't there to joke nor does he have time to waste, with the torment he lives in, pretty much sums it up.
I only used him when I couldn't use my custom character however, since the fighting styles were the same.
And him being voiced by Liam O'Brien only makes it better!
i used to be good with Ivy back when i first started playing SC2
(btw i have only played SC2 and a lil bit of SC3)
but lately since i bought it again to remember the good ol' days (got it for xbox and play on the 360)
i have been better with youshimitsu and mitserugi
(not good at spelling sorrysad )
My main up until IV was maxi but when i unlocked Vader and the apprentice those two became my main for IV. V Ezio and mitzuguri became my mains so wanted to switch it up this time maxi is a well balanced character if your not button smashing.
4laughTira-psycho, but cute. Xianghua-great for training. Viola-pretty, yet sadly like Voldo. Taki-I'm great with her in SC3. Setsuka-hate it when she blocks with that umbrella, Seong Mi-Na-it's an easy win with her. Sophita, Cassandra-they aight. Any girls are cool 'cept Talim and Ivy-pointless!
