Marth love can be reborn, if you put the time into it.
But yeah, Robin's kinda nice.
Basically Marth with projectiles that has to manage ammunition over tipper spacing for similar/greater reward (seriously that up air and fair though).
Marth's still amazing though. Just gotta get that down throw tipper uair frame trapping down to an art form (getting there, the tipper up air instead of sour up air is the hard part). But yeah, pretty easy to find a kill on Robin, but I think people still aren't used to this option-overloaded character.
