I played with the regular Razer BlackWidow Ultimate (Cherry MX Blue switches), and I felt I had a greater tendency to hit a key multiple times in a row too fast, where a few presses got missed.
It's not entirely all about the travel distance required, it's also about how the actuation occurs. Pressing past half way, but not releasing past the halfway mark, can make it very challenging if not impossible to have a repeat key strike register.
The BlackWidow Ultimate Stealth Edition, on the other hand (w/MX Browns), does not have this problem. Actually, it's highly improved in every way over the other versions. No mirror finish, brown keys, bottoming out isn't nearly as loud (better materials/construction I'd wager), and it appears the longer keys are more stable too. I think the other versions had stabilizers of some sort, but Razer did a much better job with them on the Stealth models.
I don't feel a need at all to import a keyboard now, as this one is definitely everything I wanted in a keyboard.
The Boston Dangler, I feel ya... I had the Logitech G110, and then, in the journey of finding exactly what style of keyboard I'd really prefer, I bought the Lycosa.
Ugh, not for me.
Razer has always been hit and miss for me. Some products are a perfect fit, some are terrible. Shoddy materials have plagued a few devices as well.
I wasn't set entirely on Razer for a mechanical keyboard, but I could make use of Best Buy's easy return/exchange policies and handle everything locally, at least at first.
I liked the idea of a mechanical board, but the glossy finish and noise of the BW Ultimate (non-stealth) drove me nuts. I could actually handle it, but I knew the browns would be better, and Razer notified me that the Stealths were back in stock on their website.
Like I said, the Ultimate Stealth Edition I'm finding to feel really good, and feels like it will last.
Only worried about the finish holding up over time. Instead of a mirror finish, I was hoping for just matte plastic. Well it IS just that, but it also seems like it's a coating (same as the keycaps), so it all could wear down eventually.
Regardless, it is slim pickings for a backlit Cherry Brown keyboard. Only a few manufacturers offer such a model, and half of them I'd put at or below Razer in the long-term. Ducky has a comparable model, but that requires importing, and the import sites were still waiting for more product from Ducky.
