3.5 or 5.0

Ok so in a couple months I'm going to either buy or build and order a f150. I keep going back or forth on the engine choice. The hybrid seems to have reliability problems so that's a no. So I researched the 3.5 vs 5.0 and I was and still am pretty sure the 3.5 would be perfect and more practical for towing and off-road applications with the low end torque it has. I saw some Dyno videos where the 5.0 torque is much higher on the rpm vs the 3.5. the 3.5 and 5.0 both seem very reliable. Both get not great gas mileage compared to what I have now so that's not an issue. I'm one of those paranoid people who worry about having to pack up shit and head towards Missouri when Texas starts shit or something hits the fan. Plus I like to work on my own stuff so that's where the rub is vs 3.5 or 5.0. honest opinions would be awesome. Thx everyone in advance
