Trad pub which can take years and year and requires you to get with an agent first unless you are going with very small trad publishers. (and sadly now days trad pub are sorta expecting new authers to do their own promotion and rarely offer much resources to advertise you so you are usually on your own and have to sell your book yourself. BS and is pure laziness on their part but meh). The benefit is you don't have to pay for editing,formatting or covers or getting you book in stores cus they do that for you rather then you actively doing that yourself.
Self publishing through amazon, d2d, instaspark, ect. (key note never pay a publisher a dime, if they ever ask for money assume its a scam). As someone who has research self publishing I do highly recommend it but a few caviates. You said its edited which is great, but PLEASE make sure it has been done by a professional, cus even if you read through your work a million times you will still have errors. You will still have wonky lines and scenes especially if you are new. It can be expensive as hell though especially if you can't make your own covers, or format and plan to use a full package editing for a 90K word manuscript
(developmental, copy editing, line editing, proof reading).
Also amazon is somewhat.. finicky in their terms and service, IE if you are KDP you can self publish to other stores and places like Barnes and nobles, D2D, google books, smashwords ect. However if you decide to sign up to Amazon Unlimited (which has a lot of pros and how a lot of self publish author make their money) you cant post on any other store front without risk of losing your account. Even in the case where it has been pirated so you have to prove you tried to take it down with a dmca.
