The stealth edition switches are basically MX browns. If you ever get one of the keyboards, get a wrist rest and some dampener rings. Unless your punching numbers often, I recommend the tournament edition for the small size and improved ergonomics.
I can't speak for razer's own switches, but I have a Black Widow Ultimate '13 with mx blues I got used, but the build quality on it is pretty good, and its somehow survived both the last guy who used it that I've bought it from, and then me so far. I couldn't tell you if the version with razer switches has any differences in build quality, but at least I don't have any complaints so far with mine in terms of it being built poorly, or breaking.
I really enjoy my Black Widow Chroma, unlike Corsair the software is really user friendly. I also use a Das Pro with blue switches, but after using the Black Widow I prefer it when it comes to gaming . The only issue I have with the Chroma is some times does not saving my custom lighting, which is a pain when you spend time creating it.
I can assure you that I am not a "general user", and I certainly recognize that there are far better (and more cost effective) keyboards for gaming. Razer initially sold their keyboards with Cherry MX Blue switches, which are generally recognized as being the worst switches for gaming. After a while, Instead of correcting their mistake and switching to a switch more suitable to gaming, like Reds, they created a line of knockoff switches that have the same properties of Blues that make them unsuitable for gaming. Razer keyboards are neither the best choice for gaming or for general work, and are certainly not of the highest quality.
If you are truly this uninformed about mechanical keyboards, I question your motive for participating in an enthusiast community about them.
