For battery life considerations, I'd probably swing over to the iPhone.
On a side note, everything just works on the iPhone (user-friendly and intuitive). With the Evo, yes there is mass customization but if a better OS was made, then there isn't really the need to get new apps/software. I'm not the kind of person that likes to update this or that just to make a phone better. It's like modding cars. I rather get a Corvette than to mod a Mustang to get to the same horsepower.
