10 frame jab, 13 frame 2p which is +1 on NH, 12 frame 46p and 14 frame 236p, Ein aint slow! but his strengths (mainly whiff punishing) are better suited for an offline environment, but you can say that about any character
Ein is definitely not the best character for online though the delay will REALLY fuck up the timing for his WRK stuff and his best play style is played on reaction than prediction especially when hes unsafe on almost everything. If you want to play Ein and win online you either need to be super lucky with guessing holds or play the more aggressive"online ein"
I see your point, and i don't really agree with the slow character = bad for online sentiment. Brad is slow but i think he's great for online cuz he's got mix ups for days and some of the best defensive tools in the game.
people like to shit on Bass for not being fast, but if he scores one hard knock down on you, with a few good reads it could be lights out for you buddy. in conclusion, there are very few characters where i think them being slow contributes to bad online MU's
