Funnily enough browns are suggested by everyone to the newbies, and are at the same time the worst kind of cherry switches, likely the worst kind of any mechanical keyboard.
So what would you suggest to noobs? It can't be blues or buckling springs, because they're loud, and can't be used by everybody as a daily driver, also, some may find the hysterisis annoying, although they do feel nice. Clears are hard to find and heavy, ergo clears aren't trivial to make for noobs, and end up being expensive. ALPS are friction-y, espeically on older boards, reds and blacks are linear and that may not be liked by many people new to mechanicals, Topre is expensive and arguably not even mechanical, Space Invaders, Futabas, NEC's, and all the other obscure switches are well, obscure and hard to find. Browns are light and not very tactile. Please, tell us what you would recommend, considering that switch preference is a completely personal matter?
The fact of the matter is that many people want a solid board that isn't clicky, and for availability issues, people have to tell them to go for browns. Any noob could browse the forum and wikis, and make a relatively thorough opinion on most switches, without even using them.
