Boox - Tab Ultra C Pro vs reMarkable - Paper Pro

The Tab Ultra C Pro is the clear pick on raw spec strength, leading by 19.7 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Tab Ultra C Pro if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are storage, weight, resolution.

Pick the Paper Pro if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are screen size.

Both ship with comparable waterproof, color screen, so those specs don't separate the two — focus on the differences below.

Bottom line: the Tab Ultra C Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
