Hello , I’m hesitant between buying second-hand iphone 15 pro with a perfect condition or a new iphone 14 pro ? Any advice please ?

As part of AppleCare, after, like, two years of having the iPhone 15 Max, or maybe 18 months, I broke the screen in the back, and the battery was hurting, so I swapped it for a, uh, Express replacement. The Express replacement phone is definitely the iPhone 15 Max, but the back is noticeably different, right? It feels more plasticky, it doesn't seem the exact same. I can tell the one that I already own is, more metallic, maybe, or more glassy. And the front screen seems to be less receptive, right? The original screen seems higher quality, at least the parts that are not cracked. Am I just imagining this, or is it true? Because while they are supposed to be the same, I'm not fully convinced that the parts on the refurb are the same quality level as the parts on the original.
