Jarvind said: Personally I think Yondu will be more universally useful. Big blue nuke followed by free damage (as long as you keep him out of harm's way) paired with a cheap AP destroy/strike generator makes him at least moderately useful in nearly all situations. His healing is a bit unreliable but true healing is always nice for health pack savings as well.Mockingbird seems much more geared towards PVP - AP destroyer/generator, increased match damage, and maybe free powers spells "annoying to deal with when left on defense" to me. Her red does stellar damage for the AP, but it's definitely not her "defining" ability. I don't actually think she'll be quite as good as she reads, since her powerset relies on sitting on your AP, and the AI rarely does that, but she's still one I'd think twice about tangling with boosted.In short, if you're heavily PVP focused, I'd go for Mockingbird. Otherwise, Yondu is probably the better choice.
