Keyboard buying

I’m looking to buy one of these three mechanical keyboards , and I need your guys’ reviews. And what the better option is for light-medium gaming.

1. Corsair K65 RGB MINI 60% Mechanical Gaming Keyboard (Cherry MX) $108

2. HyperX Alloy Origins 60 Mechanical Gaming Keyboard (Red Switch Linear) $134

3. Razer Huntsman Mini 60% Optical Gaming Keyboard (Clicky Purple Switch) $169

All in AUD$

I’ve done a lot of research and I still don’t know what the better one is, I’m currently using the Corsair k63 red, and its my first mechanical keyboard. So I don’t know a lot, it must be black, have good rgb, good polling rate, good performance overall.

Any help is wanted and accepted
