I came from the Imagio winmo phone. I did the hspl and used custom roms and thank the chefs for those roms becuase they greatly inproved the Imagio. But the Evo is a different story for me, I rooted it for the extra features you get. But as far as custom roms go, I see no reason I'm not into themes and all that stuff. After a few tweaks to the stock rom, it works great for me.
Whats nice about rooting is nandroid, you can install custom roms. If you dont like it you can go right back to the previous rom through nandroid restore.
So go for it root the phone everything will still work with the stock rom.
