That’s a tough question because the differences between these two solutions aren’t significant. Personally, I think the Cube System offers better value.  If you need more advanced features than what the Cube offers and a great mobile app, I’d go with the Pod Pro Cover from Eight Sleep — at least if you’re trying to cover the whole mattress.  If you only want to cover half of the bed but need a mobile app and some limited temperature control, then go with the OOLER.
