Pimax - Crystal Super vs Valve - Index

The Index is the clear pick on raw spec strength, leading by 8.6 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 Crystal Super if you care most about field of view and eye tracking. The biggest gaps in its favor are field of view, eye tracking, color passthrough.

Pick the Index 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 refresh rate.

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

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