Suggestion.

Make a list and FORMAT it in order like @Eugenius did above to make things easy to read.

At this point in proceedings I've no idea what anyone wants anymore.
Please do some self research on various devices to see what actual Hardware they contain.

A good place to start is

The Popular Hardware list and then then Google manufacturer websites for Tech specs.

All the S905 / S905X / S905D devices will run LibreELEC pretty much the same, just pick which AML chipset features (from the previous chart) and WiFi, Bluetooth and SPDIF options you want.

Future proofing and speculating that you "might need something" is pointless at the budget end of the market, because hardware changes so fast.
Buy something you will actually use with your existing Audio and TV setup.

And no I'm not going to post another DIY LibreELEC here in this thread, if you cannot follow the links in this existing Post I cannot help you further.

AMLogic S905(x) - LibreELEC / OSMC - Kodi Krypton - 4K Options:

ALL further LibreELEC support is done on the actual LibreELEC AMLogic sub-forum - ask questions over there about generic AMLogic S9xx devices.
Its simply too hard to keep up with the whole army of differently configured devices currently on sale.

Any further question about budget AMLogic devices now need to go into this thread:
