hot-swappable switches
Product 1: Corsair K70 Core
1.0

Hot-swap support is clearly absent. Multiple reviews explicitly say the switches are not hot-swappable.

Product 2: Epomaker RT100
4.7

Hot-swap support is one of the most consistently praised features, with repeated mentions of broad socket compatibility.

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.
