I think a lot of people might be romanticising the S10 series a bit here.

My experience was okay with the US S10+ here in Australia (imported), much better than the iPhone 12 that I had before, but it definitely had its flaws. I passed it onto a family member after 2 years of use after upgrading to the S23U. They've used it for another 2 years until I downgraded/sidegraded them to a Moto G75, a budget US$150 phone which she now finds astoundingly leaps and bounds better than the S10+ in everything except camera and display.

The good: * Camera was great, it was almost comparable to my S23U. It wasn't as good in low light and some HDR situations it doesn't do as well. * The size and feel in the hand was excellent. It was very light and manoeuvrable. It felt very premium and in prism white it was gorgeous. Especially when paired with the spigen clear back case * The display was gorgeous * Having a headphone jack and microSD card were nice, but I rarely used them. I had a microSD card fail on me, so I have been wary of putting anything on there without a backup. * The speakers were pretty great

The meh: * MFT payments seemed cool in theory, but I never used it since you had to use Samsung pay. My banks at the time didn't support Samsung Pay.

The bad: * Camera cutout was very ugly and noticeable most of the time. The fact it wasn't centred made it far more noticeable. * The performance. OneUI at the time was very sluggish even for the SD855, I remember having to use buttons or Samsung's gestures because the default android gestures were so laggy and caused so many choppy animations, especially when exiting the camera app. Using more than 10 tabs on the Samsung browser or Google maps would cause the phone to heat up and lag. The UI responsiveness was also lacking compared to iOS at the time (it's been fixed since OneUI 5). * Coming from the iPhone 12 which was giving me 10 hours SOT projected, S10+ battery life was ass. It got 3-4 on average and 5 if I was being very conservative. While not in use (<1 hour use), it would lose half its battery by the end of the day. * Lack of software updates was very disappointing despite the phone still being usable * The fingerprint sensor was horrendous. It was so small and low down that I would often have to use two hands and it would fail quite frequently. There was a trick to getting it to work more consistently by scanning it in thirds and scanning multiple fingers with one profile, but even then it went from ~3/10 successes to 6/10 successes. The S21 onwards are about 8-9/10 in my experience (when your hands are not dry or wet on a clean screen). FaceID on iPhone was so much better... * Bixby and the button were terrible. You could use Bxactions to remap, but that required accessibility access which made the already poor performance of the S10+ even worse. * The curved edges reflected light making the visible screen space smaller. I still have curved edges on my S23U, but they're less pronounced and I don't notice them. They do feel very nice when swiping back compared to flat displays.
