Rear shifting is smooth and fast. Totally effortless with a modern mech. Front shifting is something you just tolerate. It's maybe slightly better with an electronic mech, but still the same crude concept and never really very satisfying. Sooner or later front mechs will get replaced by something more elegant, smoother and faster (probably hub gears). There is less incentive to replace rear mechs as they are quick and smooth in their operation. It's actually a pleasure shifting up and down with a modern electronic rear mech. It's a shame the front isn't in the same league.
This looks very promising as an alternative to front shifting:-
