EDIT: Another pro-tip I have for anyone with an Android phone is to ditch Google for DuckDuckGo, not only for privacy but because it simply outperforms Google's UI responsiveness by lightyears.

My S4 (i9500) was still running great on LineageOS (some games even) right up until a few months ago [1].
Good job taking your leap. Going through the process can definitely be unnerving when you're doing it to a device you rely on (which is a large part of why I recommend doing it immediately after getting the device).
Or by all means everyone, keep dumping "old" hardware to stay on the manufacturer's software treadmill. I just replaced that S4 with an almost mint S7 for $80!
[0] I will say, it actually does end up feeling like a little bit of a let-down to get a shiny new device, do the job of flashing it, and then be greeted with the same stock LOS setup. But then I remind myself that I got said device for a deliberate purpose, and it's actually nice not having to relearn an arbitrarily different UI.
[1] FWIW, the symptoms lead me to believe it came down with something similar to "the emmc bug" that's been described for the i9300.
It's an S3 that is becoming slower and more frustrating to use every time there's an update. It can take anything from 20 seconds up to a minute to respond to a button press, and of course I'm never sure if I touched the button properly so I hit it again. It'll respond to the entire queue in a second or two, and then I need to start over.
I never owned an S3, but judging by my experience, getting root and removing all of Samsung's crapware should bring new life to an S3. As I mentioned, their keyboard software is ridiculously slow and bloated, and can make it seem like the apps being used are slow when it's really just the keyboard blocking the UI. It's been a couple years, but I remember their apps took up quite a bit of space.
By the way, another thing that could be slowing down your S3 is the battery. If it's not holding a charge well, the operating system is going to use up less power to try and stay running, hence a significant performance decrease. If your phone has a removable battery, a replacement can be had on Amazon for ~$10. Having replaced my own battery, I can say it's definitely worth doing.
Multiple apps called "messages" and "contacts", not super easy to tell which is stock android and which is samsungs? Bixby always gets in the way, where did this "SmartThings" app come from which is ALWAY in the system tray and difficult to disable and can't be removed.
I won't be buying another Samsung device, I'm not sure how they got the reputation they have.
It's an S5... And old... That's the problem.
Back when the original Galaxy S was new, one of AT&T's minor updates bricked some peoples' phones and caused many more to run slowly. I'd already rooted mine and afterwards disabled some of the offending apps that they installed, so in terms of performance it still runs today as well as it did in 2010. I just never did a carrier update again.
