Electric bass is easier to play for a few reasons. First, the action (general setup of the bass) is easier. The strings are typically closer to the frets & easier to push down. Since the pickups & amplifier do most of the work on an electric bass you can make minimal contact with the frets & still get a clean sound.
Acoustic bass sound is produced by vibrations from the wood top, so heavier gauge strings are used and are harder to press down & bend to get a clean sound. An acoustic bass tends to sound warmer because of the overtones that are present.
With an acoustic bass, additional equipment is not always needed. You can simply start playing anywhere you want. This ease of use is one major advantage of having an acoustic bass. An electric bass may require power, an amplifier, pickups, and cables etc.
Cost wise, we usually get what we pay for: tone, action and craftsmanship.
When purchasing a bass, know what works best for you. Test out a handful of basses & see which bass feels and sounds best.
