So I am almost finished with the first 121 stars of Super Mario Galaxy 1 and I wanted to ask if there was anything different about doing everything again with Luigi, is it worth doing all of it again for the 242 stars?

Because I'm not sure if I'm down to do everything again since the purple coin levels are kicking my ass magnificently, so I just wanted you guys opinion on whether or not it's worth doing it all again with Luigi?
