By electronic selector do you mean the tiptronic, or is it mech vs electric shift select in PRND?
I dislike the tiptronic because if you engine brake with it and come to a stop, you are locked in 1. I often forget about that and wind up redlining the engine when coming away from a stop and it pisses me off. I know it's my fault, but I don't like it, and that's subjective. The 5 speed is countered by the 4.3 diffs so that's a wash as far as gearing advantages, and the MPG is the same, or very close.
I prefer the four because I engine brake from 4-3, and sometimes 3-2, and you can physically feel the lever is not in normal drive so you are more acutely aware of it.
