If anyone is looking for an option that is more open with less lock in, but don't want to spend $150-300.
Amlogic S912 devices with 2GB+ of ram are constantly fairing ok across the board. The S905s were okay, but underpowered, sluggish, similar to rokus and fires, but these S912 chips have handled modern requirements quite well. If anyone was wondering which china devices to narrow their search for and keep it on easy mode, that is where I would start. I also have rockchip devices, and they are *FASTER*, almost as fast as a Shield as far as what you will realistically experience using it for non-gaming media, some faster than the newest AppleTV for your standard media services(Netflix/youtube/prime/kodi), but rockchip devices aren't as ironed out driver-wise across the board. So then you're going to be tinkering and dealing with random instability from my experiences far more often than any of the big ARM based platforms. Pi and Pi clones are.... even more of a tinker box, so I'm going to leave those out. Although Pi devices have other advantages, just not for someone who doesn't know their way around a lengthy how-to or a basic kernel.
The devices I picked up are MeCool branded, paid $55 shipped. But the MeCool brand doesn't have a lot of rhyme or reason behind how they structure their products. Thus I wont apply a blanket recommendation of their products. Rooted this one with ease, threw Android Oreo 8.1 with newest updates within like 20 minutes due to my own choice, stripped with just the streaming services and media entries I use. For $55 on gearbest, it's absolutely blowing away a Roku Ultra at $90 as far as performance and stability.
I know people pick what is best and sometimes simplest for them, so not trying to beat anything down or say one is best. But more sharing an idea for anyone looking down a similar path simply because I've been directly asked on this site a number of times, and quite honestly, my prior advise was over-generalized that I feel like the small group looking for direction simply gave up, and went back to the obvious highly advertised ones they were looking to avoid.
