Having started on electric, I had to get used to using a bit more bow pressure to get a decent sound when I started playing acoustic.  Not a big thing, but definitely a difference I noticed.

And some techniques, songs or pieces just sound and feel better on one than the other, much like happens with acoustic and electric guitars.  But I like playing both and like the differences in sound.

I think it boils down to which one you want to start with.  Look at the music you like and the stuff with violin/fiddle that makes you go "Hey!  I want to do that!" and which are they playing?

Unless you're maybe an electric guitar player and already have amps and effects, then electric is going to be more expensive when you eventually want to play with other people.

The "solid body" electrics (meaning ones that are just electric, not an acoustic violin with a pickup) have the advantage of being very quiet when you want to practice by yourself.  That can be a plus for a beginner.  I know that when I was starting on violin, I was def glad that not much of anyone could hear it unless I plugged into an amp, and it definitely encouraged me to practice more, since I could play late at night. 

Acoustic violins don't really need any extra gear to be able to play for people or jam with other players.  But they also only go so quiet.  Violin is a powerful little instrument.

Both are good in their ways, and no matter which one you start on, you're likely to need to do a little bit of adaptation and finding out what works if you later decide to also play the other.  Not a huge amount, nothing I'd call crippling.  Almost all of what you learn on one will work on the other, but may sound better on one or the other.

For me personally, I feel electric was a better first choice.  I already had amps and gear from playing guitar, and the instrument being very quiet when played unplugged or with headphones encouraged me to put in more time playing.  It also had the sounds I wanted.  Not everyone *wants* to mainly play pretty classical on a traditional acoustic violin. 

My advice would be to pick the choice that has the sounds and fits the styles that you like.  It's a simple fact that it is a heck of a lot easier to practice if you're having fun with it or at least enjoying it.  For that, you want the instrument that makes the sounds you like. 

I like playing them both.  It depends on mood and what the song/piece is.  But I do still play electric a lot more than acoustic, since I can pick it up and play unplugged or with headphones any time.  I don't know your living circumstances, so your mileage may vary on that.

But you learn a scale or run or piece on one, you can play it on the other.  They are not all that different.  I think one can learn their basics on either, and it is a matter of preference.
