Very simply, naturalization means becoming a u.s. citizen, and you get all the rights that a u.s. citizen has. that includes the right to vote. You'll have a u.s. passport, if you so choose, but it means you're done with immigration and letting them know where you live and having to renew a green card. You can never be kicked out of the country. You enjoy all the benefits of a person born in the u.s..
Anybody's who's eligible to naturalize and thinks that their future is here, in america, should explore that option. It's not too difficult, other than you have a little civics test and an english test, but we're able to help you with getting prepared for those things. My recommendation is, if you're eligible, you should pursue naturalization.
