These are great. The tactile bump is truly in the middle of travel, compared to Cherry Browns' top quarter travel, and the bump has the same duration but is sharper, about twice that of Cherry Browns.
The housings are tight, no need for films, and all of my switches' stems only had lube on the side rails, none on the feet/legs nor the flat side facing the LED slot. This is probably why they still retain their volume, which is discussed later. The springs are great, they were on average around 15mm, but they were not consistent in their coil lengths. Stock, the springs made no noise as they were oiled.
There is a bit of a break in period for these switches, to spread the lube around, but the smoothness also improves with wear as some of the switches I received, about 7 or 8 out of 110, felt like they had grooves on the stem or on the bottom housing rails initially. But once I used them in a keyboard for a work day or 6 hours of document editing, those switches matched seamlessly with the rest of the batch.
The volume of these switches is objectively louder than my Cherry MX switches (spring-swapped Blacks and Browns). The top and bottom-out of the switches are louder, probably due to the lack of lube on those surfaces, there is less scratch, and the scissor-snip tactile sound is less prominent compared to Cherry Browns. If I were to put the volumes of each on a scale, I would put Cherry Browns as 6/10 and Gat Milky Brown Pros at 7.2/10. Loud for conventional pole length, but still not reaching long-pole length volume.
Overall, these are great if you like the Cherry Brown archetype and prefer less stem wobble, a true mid-travel tactile bump, and the sound of Gat milky housings. I honestly did not even lube over the factory lube as it was that consistent, I just rocked them with my preferred lubed spring.
