My QFR currently has lubed browns for the main cluster, while the rest is still lubed vintage blacks. Even though I do think that linear switches are best for games overall, I was getting slightly bored with my vintage blacks so I decided to add a lil' bit of tactility by adding lubed browns (ergo clears were fine for RPGs games and what not, but too tactile for FPS games). They don't compare to ergo clears or vintage blacks in terms of feelsgoodman level, but I think they are an awesome gaming switch.
They are what you'd expect them to be; they are in between ergo clears and reds in terms of feel. The tactility is present and quite noticeable but not enough that it'll interrupt your keystroke when spamming in between multiple keys. That said, you will obviously feel less tactility the harder you're spamming keys, but if you're playing something like FPS games, you'll definitely feel the small tactile bump, and probably less so with RTS and MOBA games. I have a tendency to press down more softly with FPS games. You'll definitely feel the tactility though when you're just typing, and this is where I much prefer ergo clears or just plain vintage blacks/reds. Like stock browns, I feel like the lubed browns are just an efficient switch but only decent in term of the feels, and because of this, it makes it less desirable for typing IMO; it's not soft and clean like lubed vintage black/reds, and it's not satisfyingly tactile like ergo clears. Kind of a Jack of all trades, master of none. I would change it back to lubed vintage blacks but I'm too lazy to right now

Also note that your feels will vary depending on how heavily you lube. I used Krytox mix for the side of the stem, and didn't lube the slider itself as there was already some present on the leaf of the switch from the previous lubed vintage blacks. I then used Victorinox for the hole in the bottom switch housing, some on springs, and bottom of stem to dampen sound.
