Agree with Matoya. Hilda could've been cooler but I think she just didn't have enough screen time. I'm sure we'll see more of her in the future though. Also Fray from the DRK questline. It's a pretty interesting chain.

Gunu Vanu was incredibly annoying, I can't believe my character felt compelled to help with his blatantly stupid endeavors. To be fair to the Moogles, all the sidequests are more streamlined and a continuous narrative now - it's easy to point the finger at them because it's all coming from the same source, whereas in 2.X they were equally as dull / annoying just from different sources.
