What is the best value iPhone to buy in 2024?

I’ve been using an iPhone 7 for over well over 7 years now, and I’m thinking of upgrading to a new iPhone but I’m very confused about which phone is worth buying now

(My budget is 900 dollars, and when I asked relatives who understand more about modern phones that I do, they suggested the iPhone 15 plus or the iPhone 14 pro, but then when I did some more research I saw some people recommending the iPhone 15 and iPhone 14 pro the most and saying that the iPhone 15 plus isn’t worth buying, some people also do believe that it’s up there with the 15 and 14 pro but it’s hard to decide)
