Heres my experience with starfall.
It was sorta a pain downgrading to 3.2u, but installing Starfall was easy. The main reason I wanted starfall was for the recovery menu +autoboot feature.
Basically, I play a lot of Brawl, and I don't like having to get out a Wiimote just to start the game. I simply stick in brawl, turn the system on while holding Y on the 1st gc controller, and Brawl boots.
This also lets me have more freedom with testing out wad banners. I can install a WAD, become banner bricked, then autoboot zelda, use tphack to run wad manager, and uninstall the broken wad.
Thats something that is worth the trouble.
