The most important thing is that the timbre is different, and the electroacoustic one is slightly worse than the traditional one. In fact, according to my experience, buying mandolin mainly depends on the choice. The goods on the market are mixed, and it cannot be simply said that whose timbre is better than who. Actually, it's all the same if you can play.
Again, just pick one that is easy to listen to after you can play it. Beginners don't need to care too much about this.
