I like how fast I can type with them; barely have to press them for actuation. I don't like how heavy they are when pressing down on them, despite how fast I can type with them, it gets tiring after a bit. They're scratchy without lube, and after I lubed them, they were really nice and smooth with a tiny bit of texture you can feel/sound while typing. Depends with the build you're going for. I think I would reccomend them for a light low profile keycap. As for sound, they sound a little more dense than the general linear switch, but that's just with regular PBT XDA profile keycaps.
Overall, great for the price.
