It depends what you're looking for. In the AV enthusiast circles a lot of people flock towards the Ugoos AM6B Plus (with CoreELEC).

It is one of the only devices (alongside Oppo clones) that can play Dolby Vision Profile 7 FEL (Full Enhancement Layer) with 100% accuracy. The Shield can play P7, but it ignores the FEL data; the Ugoos actually processes it.

That said, people don’t generally use Android on it, instead you boot to CoreELEC from an SD card and use Kodi.

I have an am6b+ but in reality the shield is a much nicer device to use if one wants to use anything outside of their local media.

I actually wish we could run android in a container on the CoreELEC side and switch back and forth between Kodi and the android UI/apps (without needing a reboot, and having a better managed android environment than the provided one).

The unfortunate part is that CoreELEC only works when you get all your content from a locally attached disk. You can't even really stream it from your beefy NAS/server, and you definitely can't use any streaming services.

I'm constantly surprised how many people are in that narrow category of just dipping thier toe in the water for "self-hosted" content that it's little enough it fits on disk storage you can have in your living room (mine is a half-height server rack in the basement), but also have progressed past thr point of using any streaming services. I guess there are a lot of people without families that also never travel out there.

CoreELEC is a godsend for FEL compatibility, IMO. With a little luck, you can get a device to do FEL for under $100, and you don't have to deal with some random, poorly maintained Android release that probably won't keep up with security updates, etc.
