Put me in the category of not wanting to roll back. i'm a little upset about not being able to download the latest maps but overall Froyo is just plain better then stock 2.1.
I don't know how it compares with rooted 2.1. For me I like it better. Hopefully the apps will start building to 2.2, but probably not until there is an official release.
heres a fix to be able to download the latest maps for froyo....
