Product 2: NuPhy Air75 V3
4.5

Hot-swap support is a well-documented feature and a consistent selling point across the review set.

keycap quality
Product 1: Corsair K70 Core
3.3

The ABS keycaps are generally seen as usable and reasonably grippy, but they are not treated as a premium highlight and one review was strongly negative about them.
