Barbarian’s are fun, and can be straight forward if you go the charging route. Thaneborn, (Which your +Cha from race helps) can be a bit trickier, but in the end, you still smash stuff. I’m a big fan of Barbarian, and have one going the charging route in the L4W side.
Charging, usually a Rageblood Barbarian, generally focuses on Howling Strike, and stacks as much stuff onto his charge as possible, Vanguard weapon, Horned Helm, Iron armbands, Badge of the berserker, Powerful charge feat, etc… They then charge around the battlefield like a pinball. Thaneborn can act like a quasi-leader type with some of the group buffs they can provide. Very useful, but less damaging than the charger. Whirling Barbarians can do some amazing things, but can be tricky to keep track of when you can shift where and what bonuses it will give you. I have never seen the 4th type ?Thunderstomp? in action, so alas, cannot offer any aide on that.
I think you picked well going Barbarian, now you have to chose a style!
