Acoustic is more immediate fun without the obsessive knob-twiddling. You strum an acoustic and as you modify your fingers it can start to sound good straight-away. Of course you still need to learn and practise but the promise is there from the beginning.
Electric is more tricky, I find I'm tackling sounds that sound energetic but actually arise from light and precise plectrum strokes. Oh and each song has a 'right' sound arising from the at least 5 parameters and that's with the simplest beginners rig. Electric can distract you from actual playing with a detour into amp sounds, effects boxes, modelling, hot rodding...
The 'Fender Presents' Electric DVD is well regarded but get yourself on a lessons as you'll enjoy it so much more.
