Which is harder to play?

TOTALLY it is the Acoustic. HOWEVER, acoustic will force you to play better (because it less forgiving), thus you will play your "Fat Strat", or your "Les" better as well.
Acoustic forces you to "fret" the note or chord better (closer to the fret bar) or you will get a lot of string buzz that sounds like crap. You can get away with that stuff on the elec with no negative results.
I have a tendency to sit on the couch messing around with my Strat. It takes much less effort than my Guild. I sit up and pay more attention with the Guild.
Important safety tip:
I mostly play my strat un-amped, as it makes little noise, and draws little scorn from the family as a result.
As my old teacher used to say, "everybody loves a good guitar. Everybody hates putting up with what it takes to get there".

Yeah... learning on acoustic makes you the better player. It kind of forces you to hold done every note, basically keeps you from being lazy... and thus makes you a better guitar player.

Before you know it, you'll end up like this...
