The gain difference is meaningful
The PET Crystal Classic’s published 0.85 gain is higher than the S PRO P’s 0.6. In broad terms, lower-gain UST ALR surfaces often prioritize black level and ambient-light control, while a higher-gain surface returns more projector light toward viewers. Neither number should be interpreted in isolation from the projector’s brightness and the room’s light.

Check current price ↗Controls and automation
Both products are designed to make the screen appear only when needed. The VIVIDSTORM listing emphasizes RF control, app control, voice assistants, remote height adjustment and USB trigger. The PET Crystal Classic listing emphasizes voice control and projector-synchronized rise/fall via USB trigger. If automation is a deciding factor, confirm the exact accessory/control bundle for the size and region you are buying.
How to choose without overfitting to a spec sheet
Use the comparison to narrow the shortlist, then check three concrete things: your projector model, your room lighting at viewing time and the exact case dimensions for your furniture layout. Current regional pricing can be a larger practical differentiator than a small paper specification gap.
