The SAS only by a small margin. Put it this way, their training is a lot more rigorious and they use real bullets at all times. I mean, people have died during SAS training. You don't join the SAS, you are chosen. I mean, the Seals probably have a slight advantage with the weapons, but from what I've learned over the years about the SAS is that failure is not an option with them and they always get the job done. They're just more hardened and innovative and although it's very close, the SAS would win.
