No its good but like most of her attks the "box" on them are soo small that it request flawless timing and i do not know if it will out rng your air attk so i just stay away from it all together. Also a lot of her attks do not come out the sec you hit the butter there is a slight delay to them making timing soo much harder. I saw when you where playing zss you spamed her air N but you only landed a few hits because its hard to hit ppl with a sort lived attk like that. This may be the reason zss not seen as a top tear chater too because most of the top tear chaters have a long ish lasting attk. The attk may do less and less over time but it stays out there for a nice bit making counter attks harder to be done.
