Fretting?
I certainly wouldn't spend any seconds fretting about whether to install something from GAOTD.
Starburn is wizard driven, with big buttons and lots of functions (grabbing, decrypting, shrinking, burning). More functions than many progs; works OK. You probably don't need it if you have Burning Studio. You very easily may not like its interface; it's the antithesis of techie, but there is an 'Expert mode' with extra settings.
Does more than ImgBurn.
I'm not saying anyone
should try it. I have a lot of burning progs and could probably get by with any one of them. They all work a bit differently and I just use the one I fancy at the time.
