I got one of those testers with 6 keys, a few linears of varying weight, a tactile, and two clicky. I liked the medium linear. I picked a medium weight linear switch mostly at random because I liked the color, Durock Lupine. I'm very happy with them. At the end of the day it's the hand lubing that makes them feel crazy good. Which one you pick barely matters in the beginning because you haven't developed your taste for this stuff yet.

So get a tester, let it push you in a direction, then just pull the trigger on something. All the recent switches targeting the hobby market are good for one reason or another.

This subreddit is you listening in on the people in the box. You haven't spent years in the mechanical switch box yet. Their opinions won't make sense to you. And when you do have a few years behind you, you'll disagree with most of them anyway. Have fun trying stuff.
