There are pros and cons to both... they are two different beasts. I agree with what most have said... follow your heart. Whichever one you love!
PROS...
Acoustic
- Hand and finger strength develop faster...
- ease of travel, no electricity
- you can always buy an acoustic that plugs in so you can use effects n pedals 2
you can have it both ways...
- the 'woo' factor
Electric
- dexterity usually develops first since most beginners drift toward licks/shredding... hard to resist driving fast in a race car
- the effects and pedals and amps to pair with your electric are endless
- electrified music is more prevalent today than ever so your options are more.. acoustic punk rock hasn't exactly taken the world by storm yet
CONS
Acoustic
- smaller niche
- gentle nature makes it perceived as less bad ass and less exciting on the whole.. it may seem less thrilling ( not my opinion but many see it like that )
- if you electrify it, most won't know the difference but it is an acoustic
Electric
- have to have power source, cannot take it just anywhere
- more money invested... now come amps, pedals, effects, etc
- can distract/overwhelm you needing to know so much more just to play
- amp factor with neighbor factor, they are a bit more ferocious and like a race car, you wanna drive fast and loud... be respectful and get good headphones then. That way you can practice all you like at any time day or night
Hope this bit helps as well
