I read it the first time when I was 13, and I loved it. A lot depends on you -- but don't let your experience with Romeo and Juliet decide for you. The language cadence is totally different.
Give it a try! When I read it at 13, I read it as a straight story and loved it. I got some of the more overt wit in it, but mainly just the story of the main characters. Since then (I'm now a grandmother) I have read it nearly every year for about 40 years; and every time, I read it a little differently based on where I am in my life. When I read it in my late teens/twenties, suddenly I understood the irony and the subtler wit. Still more readings and I began to see Jane Austen's immense understanding of human nature; her mastery of crafting not only plots, but details; her wonderful use of language; and all sorts of other things. But don't worry about getting all of that in a first reading at your age. Just read it, get from it what it offers to you at this point in YOUR life (there's no law that says you must be able to dissect and analyse every nuance of it, just enjoy the story and Elizabeth Bennet and Mr Darcy) -- and I suspect that you will love it... and maybe you will also reread it once in a while as you grow older and love it just as much for different reasons.
No research, just about a hundred readings of the novel over 45 years! LOL
