Pros: Better field of view because face is closer to lenses. Better light blockage, light filter does help but comes with tradeoffs (see cons). Swappable inserts for sharing or for longer sessions.
Cons: Sticky, the material doesn't absorb moisture, but is stickier and less comfortable than OEM. Foam has higher IFD rating than OEM and a lot foam, causing movement more harsh. Narrower than OEM and causes additional pressure on the face, a big negative that already comes with owning quest. Nosepiece blocks exhaust so I had worse fogging even with the added ventilation.
