>>108726771>Phineas and FerbBland as fuck main cast. Followed the dreaded "segmented with b-shows" thing like Dexter's Lab. Too many songs. Dragged on far too long and pretty much no one noticed when it ended.
>Gravity FallsMain cast was generally entertaining. Full length episodes. Things only got bad towards the end, but the general complaint is that it ended too soon.
Not even a competition. P&F was just Disney Channel's answer to status quo heavy, everything goes awry Seinfeld for kids type shows like Dexter's Lab or FoP. Don't get me wrong, it was a big success (mainly because Nick and CN were at rock bottom at the time), but Gravity Falls eclipsed it in every manner.
