I have a Venue 11 Pro and for a while I had a Pipo W3, in my opinion the speakers were nowhere near as good on the Pipo so I think you’d be better off with what you have. Frankly the Pipo I owned was a disaster, there was more than one hardware issue. I would never buy anything from Pipo again after that tablet.
I don’t think the Cube Remix will dual boot, so that might not work for you either. The only Cube I currently have is impressive in terms of build quality and is still giving good service after a little over a year of heavy use (the battery doesn’t seem to have deteriorated at all). None the less the speakers are poor, but I have headphones that are good so I don’t care π
