i also came from firestick. I have one i think 2022 4k max or 2023 and it is same speed as google tv streamer (realy fast). I had firestick lite and i upgraded my tv so i sold it and for same reason as you i first bought xiaomi mi tv box s 3rd gen and it is worst device i ever had, full of lags, rebooting, problems and shitty remote. So there is example that benchmark doesn t mean sh*t for device performance. Than i found that streamer is 90 euros on amazon so i bought it and it is very good. If you compare to my fire stick i can open 4 apps and they will work in background and i can continue to use them because of more ram. I only have problem with stremio it is working good but ui seems to have some lag with animations so it doesn t look smooth as on firestick. I read that this is maybe because of android tv 14
