are c5 autos that bad?

i was thinking about getting a c5 z06 because i wanted a fast/quick car that i could afford. unfortunately, i don’t know how to drive a manual, and i’ve seen a lot of people say that the 4L60 is not very good, saying its slow and slips and will probably have to be rebuilt. i don’t feel like learning manual (just because i need an everyday car and the area i’m in gets crazy at times with traffic) but is it really that worth it? if i can’t rip the c5 from time to time then i’d rather get a 4 series bmw however if the auto isn’t that bad then I could just get one. i’m down to get a manual if needed however. thanks!
