Well, if you're someone who's mostly into the phones then, Samsung is no doubt your first go as they provide customisations, tons of exclusive features like Secured Folder, Window mode, easy multi-tasking and of course world class displays.
But if you think you need a piece to show off and if you're not much a phone-person then get an iPhone.
i just made switch to iPhone 11 pro and i think it was worth it. yeah, as everyone says that it is less customizable but it won't bother you as all operations which are available on IOS are all flawless, you won't get any lag. I definitely suggest you to go for IOS.
For the battery it's far better than Samsung, with moderate use for full day i still get 20 to 25 % battery left at the end of day. and with low use or no gaming or very low gaming it can give you almost 2 days of battery. About the RAM, it's enough your game won't lag at all nor any other app. though as the RAM is only 4 gb some applications will reload but that isn't much of a caveat as it will open it very quickly. and one more thing which i obsessed that every exynos Samsung device overheat with very little use of camera and that was the major reason for low battery life, but in the iphone your phone barely heat little bit with any high usage so that won't be an issue on iPhone.
