Wondering best guide to use for setting one up launchers iptv I use tivimate. Seems to be video for older models wondering what best setup is currently. root/ no root, side load, what to disable etc

All my devices are max 4k 2nd gen. Had two of them brick this week and get stuck in boot loop for no reason. I'm done with fire stick devices. So I'm looking to replace 5 with something thats same or better specs in the same price range. Any suggestions?
