I don't know. For one, Ryu's light Ftilt makes his foot partially invincible which no other character I know has. So, Captain Falcon, Fox, Falco, ZSS, Mario, Greninja, Luigi, and Samus basically all have angle-able, but not as safe Ftilts. Or something like how Yoshi's st. grab is frame 14, but his dash and pivot are frame 10 with about 46 and 44 recovery frames to his st. grab's 31. In a way, it's Greninja's situation where his st. and pivot grab is much slower than his dash, but have lower recovery, except in his case, st. grab has 13, pivot has 20, and dash has 27 which are overall lower than most characters.
Speaking of Yoshi, I have no idea what the point of his Ftilt is. It has short range, does 7% or 8% angled, and while it's fast at frame 5, and has 3 active frames, it has 38 total frames. That's 31 recovery frames. For a poke move, that's really bad. At least his Utilt and Dtilt have low recoveries at 16 and 13 which kind of justifies their short range as well... Still, they can be disjointed all they want, but he has like shorter than Mario range for tilts.
