I've used PS on windows, of course Gimp became my main photo editing program when I started using Linux. Because I'm just an amateur, can't do any comparison, also can't say that I miss any of the options which comes with PS.
But I liked this, have installed it and it works, except for the launching. Somehow it does not add it to the menu under the Wine apps. But I can launch it, navigating to the installed folder.
Ps, have not installed Illustrator, because I have never used it.
