S1. I have a bravo and I don't use it much since I got my s1. I am not a fan of the waxed micarta. Nor the thumb ramp. It did chip up easy as well so the steel was a disappointment. The bravo 1 is also extremely expensive. In a 5 inch I think there are better option for far less. I found mine in an s1. Handle is much better IMO, grippy, eats up shock, great when wet....however not as durable as the bravo 1. I actually like the cheap slim s1 sheath better as well, initially I hated it but once I used both for a while I realized the s1 stealth worked better and was far more versatile and narrower. I wrapped it with some 550. The s1 is also lighter, might not be as thick but still around .200 thick so it is no slacker.
