I had a cherry MX brown PLU ML-87 and Noppoo Choc Mini with Browns as well. There sounds were very different. I liked the sound of PLU ML-87 a lot more because it felt like a lower pitched click, the Noppoo on the other hand was very different. Its hard to explain so I am not going to do it. It seems like the sound could be affected by the types of keycaps used.
