So while in New Mexico I payed special attention to my ftilt usage. It's really my staple move and 75% of my ground game. Jab, grab, turnip stuff, with every other hole covered by ftilt. I'll see if any of the replays can get recorded - but after NM, I'm more than convinced it's one of her top ground options.
Maybe it was rash of me to call it better than Snake's utilt (I see how he utilizes that type of move better), but it's more than comparable as a spacing tool. As that type of spacing tool, it's always gonna score higher than fsmash.
Fsmash is an amazing option, but it's forever going to be stuck as a defensive move. Even then, you can't punish a properly spaced MK dsmash with fsmash out of shield, while ftilt can. You can't punish tornado on reaction with fsmash, while ftilt can. Fsmash even has more cooldown than ftilt, so it's not even safer (ignoring it's excellent pushback).
Ftilt's speed gives it the flexibility to not only use it offensively, but as an instant defensive option. Fsmash, much like fair, needs the space and time to work effectively. Ftilt, much like bair, is the perfect compromise in speed and range, which comes in much more useful in everyday action.
Ftilt is the ****.
