I agree with redchevy. The ED is slow from the line but has plenty of passing power on the highway. I have passed people with my bass boat behind me on 276 between here and Fork.
As for the ED vs EB debate, I think the comments above are right on. They are different beasts. The ED will get considerably better mpg but won't be as fast. It'll also be a little cheaper to buy and a little more expensive to maintain.
As for gas vs diesel costs, usually gas is cheaper when it's under $2.50, diesel is cheaper when they're above $3.50, and it's about a wash in between.
If I had it to do over again, I'd buy the ED again in a heartbeat. I have an app that measures my actual gas mileage (towing, city, hwy, etc.) and I'm getting 26.5 mpg. If my commute was 40 miles instead of 15, my mpg would be well above 27. The gas mileage on the ED is significantly better after 10 minutes of driving when the engine warms up.
All that being said, it's worth noting that the ED doesn't do all that well if you drive 75-80 mph or more. I'm sure the EB doesn't either, but I've slowed down from driving 75-78 on the highway to driving 67-68 mph. I think if the engine was warm, I would still do fine at 72-74 mph, but my commute is just too short to drive it hard with a cold engine and expect good mpg. But I think if I had a long trip and kept it at 70 or under, I could probably get 28-30 mpg. It's a really amazing truck. I love it.
