I really want to master an IDE and vastly improve my programming skills so that I can develop commerical quality software products and work as a programmer. I am also learning *nix right now and noticed KDE comes with a integrated IDE that supports like 14 languages.

So which one should I really spend alot of time with familiarizing myself with? My strongest lanuguages are C/C++. Are there pros and cons to each IDE? From what I read, the KDE K develop is on par with visual studio .net, anyone know more?
