Well, depending on alignment, Paladin or one of the alignment variants wouldn't be a bad idea, particularly if you are using Sorcerer as the casting side, since you get your casting stat to all saves. Immunity to fear, Turn Undead can be used to fuel Divine Feats.

Hexblade is also not a bad choice, being full BAB, getting Cha to all saves, Mettle, and while the fourth level is a wash, it's still not bad.
