I have the 83mm with plain blade and like it fine.
Had a 92mm plain been available, I would probably have opted for that but they had pretty much disappeared unless you wanted to pay a premium and the slight difference in size was not worth it to me.
Seems like the 92mm black is the most popular, with the 92mm's in general being the more popular (bigger is always better right? ).
The safety on mine is solid, no rattle.
From the user comments I've seen, the noisy safety is just a mild annoyance and doesn't effect usage.
