Electrics are often much more fun to play, but I found, early on, that the acoustic gave me better habits, and made me a better all around guitarist.

I bought probably the exact same cherry Epi SG a long time ago to start off with, and I can still remember how embarrassed I was the first time I tried to play an acoustic.

Conversely, for a long time, whenever I was having trouble learning something on the acoustic, I could swap it out for an electric and usually just bang it out. Perhaps psychosomatically, this then made it easier to play on acoustic, just knowing that it was playable.
