I opted for the 53/63g springs. They have a really sturdy feel overall with very little stem wobble. There is much more up/down wobble, and almost no left/right wobble. I can really only notice this if I make an effort to get them to move up and down.
On my Weikav NUT108, they sound extremely pleasing. Slightly clicky, but only in the mid/low range of tones and nothing in the high end. Almost trending towards a thock. Depending on your board this might not be the case.
Overall these are a fantastic choice for both typing and gaming which are my primary uses. I will say that think I would prefer an even heavier actuation, as I'm having a couple accidental presses during games but I think some of it is switching to a cherry profile keycap from OEM style.
Also, shout-out to Peter. Great customer service. Thanks!
BeaverKeys - the seller service is 10/10.
The switches feel great (53/63g) - no accidental presses, consistent lubing, and great quality. I’m not the fan of the sound as it leans towards clacky but it grows on you. Maybe because I have always had silent or thocky switches. They have almost 0 stem wobble - probably the most sturdy switches I have tried.
