I have in my collection the 2015 13" Pro which is a fair bit different from the 15". Worse performance, of course.
The 13" has one of the relatively rare "Broadwell"-processors (Intel's first venture into 14nm) which incidentally has Metal 2 support. This could have an impact on how well it gets supported on Sonoma and further on. I don't believe the 15" have this, as it uses a Haswell CPU with a slightly older iGPU. Of course many 15" shipped with a dGPU as well and are overall just significantly more powerful machines due to this and having quad-core CPUs instead.
When it comes to performance.. It's "fine". I'd say what it could be used for back in the day is what it can be used for now: web browsing and more basic office stuff. It simply lacks the oomph for anything else. But browsing is a totally okay experience. The screen is extremely nice compared to that era's Air-model.
I've tried Sonoma on it thanks to OCLP and it worked though the live backgrounds were pretty laggy. One OCLP update bricked the install so I went back to Monterey.
In many ways it's a good year for the MBP, though. First MBPs with force touch trackpads. Glowing logo. USB-A is super duper useful still. Thermal headroom without death-throttle! (I know M1/M2 Airs throttle as well but with Intel you could reallly really feel it. It was on a completely different level during the Macs' 2016-2019 era)
I totally get having an old Mac to just play around with or gawk at, so I'm not gonna say "go M1 Air" though that advice pretty much always applies normally
