These aren't like WM. There are no quirks or disabled features in them. There were a few bugs in the early roms, but now, not so much (unless you flash one that has the 2.1 launcher). Many of the roms containing the 2.1 launcher are buggy and laggy, but it pertains to the launcher itself.
These roms are very similar to stock, just with added features that can only be done with super permission (rooting) such as: Overclocking/Underclocking, WiFi Tether, Live Wallpapers, Theme changes, etc.
I am running Droid Mod 1.0 and EVERYTHING plus some works perfectly. You can customize what you want in the rom when flashing, and if you don't like it, just go back to your nandroid backup and it'll be like you never modded anything. If you want to unroot, just flash the stock 2.0.1 in the DM Updater. Trust me, flashing Android is very different than WM when it comes to flashing roms.
