My opinion on stock: Let's have as many people devving for it as possible!
Stock rom sucks. It has many problems/glitches, both in the aesthetical (a custom theme that doesn't go well with many apps etc.) and technical aspects (people report problems with bluetooth, wi-fi, FC of some apps etc).
At least games perform very well as far as I am concerned, high resolution movies/videos too. AndyPad Pro here, by the way.
I hope someone appears with instructions and a good working rom replacement for this device, because the official rom never got the love it should by its original developers...
