Which do you feel is better? I have a feeling many of you are going to take the latter, but I'll go with Sunshine. I've completed Sunshine (90 some shines), and I'm almost finished with Galaxy, and I can pretty much say Sunshine is my choice. The main reasons for me are because the control of Mario in Galaxy seemed, for lack of a better word, dumbed down, and the linear path of each level/galaxy. Seemed like Mario Galaxy had very little exploration, and that's one of my favorite aspects of Sunshine (and ofcourse Mario 64).
So what do you say?
