Lyric Thaumaturge vs Heartwarder?

[Masakan]

Without any sort of context, which would be better for a battle bard?
And if the answer is neither which would you choose?

And yes Im set on dodge and mobility because im determined to get elusive target, besides you can get mobility as an armor enchant easily anyway.

Probably Lyric Thaumaturge. The chassis is sturdier, and you can make good use of those extra Sorcerer/Wizard spells. Heartwarder's inherent bonuses to Charisma are nice, but if you ever end up getting a tome of leadership and influence, it doesn't stack.
