Torn between two patch 8 subclasses

I'm basically excited to try almost every new subclass in patch 8 (Xbox insider hype!) but I've settled on either trying Bladesinger and Giant Barb. But I can't decide! I know I can fill either of these roles with a party member, I'm just trying to figure out who my Tav should be.

Anything I should know that might tip the scales in one direction or the other? I've had frenzy Karlach barb before, but I've never really used a wizard proper. If I bring gale, I tend to class him into something else. So maybe that is reason enough?

If I was to do Giant Barb, I would want to do "Idiot Savant's Telekinesis" if you will. Focus on throwing enemies for when I need ranged attacks.
