Had a 13 pro too, and made the switch.
The most noticeable thing for me, is that it’s way more comfortable to hold, 13 pro dug more into my skin than I’d realized, and was heavy to rest on my pinky. I’m ok with the weight on the 17 pro because of better edges, and I don’t feel the strain on my pinky.
The brighter display really helps in the sun.
The telephoto lens is nice, it’s great for documentation purpose. Overall better camera is nice too, although it’s not replacing my real camera.
I was happy to find out there is a new camera button and a multipurpose one, though I don’t use them that much.
That’s the biggest changes in noticed. It’s faster too, but old phone was enough tbh.
What I don’t like is that back is more ugly, and the glass cutout is not well made (not centered and not level with aluminum frame). Might just be mine, but I find it to be sloppy build quality.
While the new camera cutout is ugly, it’s nice that it rest more evenly on a flat surface. That was annoying with the 13 pro when you used it laying on a hard surface and it wobbled every time you touched it.
I preferred the notch, I’m not a fan of the pill cutout.
Better color options would have been nice, why still no green :-( But most I really miss an all glass back, it looks WAY better and was so scratch resistant.
While the upgrade does not feel like a big jump, it had enough small useful features/upgrade for me to be happy enough, and I’m sure it’ll last for next 5 years easy
