Thancred will always be that stupid guy from that sends me off to do all the work for him while he accomplishes nothing (The Ifrit storyline and Lahabrea bits are to blame for this) he's kinda cool in the Leviathan arc, and maybe a little cool in the 1-15 story (definitely showing he's not completely useless). He's quirky and that's all he's got. Yda's quirky too, but her dynamic with Papalymo is hilarious and it explains why they take a backburner role as they bicker, and Y'shtola comes across as thoughtful and thorough so she doesn't seem like the type to just dive in. Thancred comes across as the type to DO something like Yda, but the fact he DOESN'T is very off-putting. He just comes off as lazy to me most of the time.
