Switching from iPhone 7 Plus to what?

Hi! I have an iPhone 7 Plus and I'm ready to upgrade. I know the new iPhones are expensive and all. But I can pay monthly. But I don't know if getting the newest one is worth it. I saw the iPhone 8 Plus and I heard it's almost the same thing as the 7. I like my screen big so I'm not sure about the iPhone X. Anyways what do you guy think?

Have you compared the specs and decided that the new versions have something you need, or are you just trying to show your friends you have a newer phone? I own Apple stock so I would love for you to buy a new one, but it's probably not necessary. I still use an iPhone 6 because every year I compare the specs with the new versions and there's nothing new worth paying the price for. But go ahead, buy the latest version and help fund my retirement.
