I agree with what's already been said they are both great imo. I have several caniks (t100, p100, t120, p120, s120, shark fc, tp9sa) and a couple SARs (b6p and k245) and all are good solid pistols with only a couple issues with the finish on the t100. I would have one of the SAR mega in stainless (aka previously imported SAR b6 hawk) but I was kind of waiting for them to get under 400.
My thoughts on the SAR/EAA break is that the SAR pistols were going to (or already were) steal sales away from the witness line so EAA only imported the SAR pistols that were a little different than the witness line. For instance the b6p and the witness ps are almost identical other than the accessory rail on the witness. Anyway, as others mentioned SAR probably wants to bring in their entire line and EAA didn't. Good for SAR to try to do it on their own, I wish them success. I could see them doing very well with their entire line available here.
The B6P is one of my favorite CZ75 type pistols and I'd be hard pressed to get rid of it over some, if not most, of my caniks. Take that for what it's worth.
