Your question will start the engine wars again, so be prepared.
I had some of the same reservations when I bought and after driving both, chose the 5.0. I have 23,000 miles on it and love it so far. Just last week, someone posted that there was some evidence that the EB was having problems with the direct injection system. Don't know if there is much to it or not, but something to watch for. On economy, after reading all the posts on this site, it seems to me that the EB does great if you stay out of the turbos, but if you drive it as I normally drive, the mpg is not all that great. I'm a grandpa, but do not drive like one, and get great mpg out of my 5.0. I do not do any heavy towing, so the extra tow benefit of the EB is of no value to me.
