QtCreator is fine, but also I good option for me was, Eclipse with the Qt-plugin.

I agree with you, I was using eclipse for a project in the past and it puts more than 1MB of plugins and other stuff in each project that I used, I've been using netbeans for a year and a half, and since than I dond't want to change it for nothing, sometimes it is slower, yes it is, but I prefer the syntax highlighting, better than visualstudio, that lacks with a simple brace highlight And after I learn hotkeys like ctrl+1, ctrl+2, and others, I don't wanna change it for nothing. Other good pro its the code models that really helps to speed up the coding. One cons is that subversion plugin that comes within netbeans it's slower than running a command line to update or commit,
