"Easiest to live" with and "most fun" are often in conflict with one another. The Coyote aluminator would probably be the easiest to live with given it's variable timing, computer controls, fuel injection, and factory engineering. For old school rumble and shake and kick you in the back torque the 427 and 428 motors (and any variations) will get it done but it will probably have a few
oil seeps, require more tuning and attention and quality /durability will be greatly dependent upon the builder. Your right about the Coyote won't have as much off the line torque and kick in the back but it will pull longer - sort of like comparing a 396/375 Camaro to a Z28 Camaro back in the 60s.
