I’ve used many throughout the years. There’s always something goofy going on. Watching something on input one might automatically switch to another input that is just doing a network software update check in sleep mode. Or someone picks up a game controller and accidentally presses a button which will also suddenly switch inputs.
CEC is only good if the devices connected to it are very limited and if you want to do all software updates for everything manually.
LG's implementation is both good and bad. It doesn't automatically switch over, but it pops up a dialog box asking if you want to switch inputs whenever another input is connected or device turned on.
Samsung did neither, and I always had to manually switch inputs.
