I still use homebrew. I don't go on homebrew games because, to be honest, they aren't so good as ISOs. But there are some amazing plugins out there which I love and emulators and certain file readers are very useful.
I agree with QueenB; ISOs have killed homebrew, but then again they existed long before homebrew came. But the big difference is that ISOs are made for money, not for fun, so you don't get the same sort of feel that someone has given up their spare time to make something you can enjoy.
