My Samsung s9+ with Evolver Android 13 custom rom (and duo sim) is still a very good phone. Amoled screen, good camera and battery life still over a day when setting the brightness not too high. Not a scratch on it too. I don't use it daily though as it is a very big phone, but I take it when going out or on holiday because the camera on my iPhone SE is crap and as you mention for gaming.
I have been repairing tons of these phones here in the Netherlands and it is just a very solid phone that is very easy to repair. The s10 for instance comes with a single board instead of sub and mainboard like the s8 and s9 series, so when something is wrong with a USB, like not charging or connecting to PC or the mic doesn't work the board get's scrapped for usable components and these components come back on refurfed boards that we get back from Samsung (those are often a pain in the ass prone to not pass the quality checks after repair).
I still use an iPad 2 for making music and as MIDI controller for the Home Studio, I just dislike to throw away perfectly good hardware, as is my s9+
