I'm not sure whether it has been mentioned before, but here's a video review by a Youtube outdoor channel called Backwoods Pursuit. It's 18 minutes long and seems quite balanced, not prone to extreme wows or arrrghs to praise or criticise, so a nice view overall
I'm not sure Sig Zulu 6 are easy to find over here in Europe, so I've never seen or tried one, so nice to hear from someone who has tried the whole 32-42 mm range and compared them. Reading here and there I got the impression that the Sig Zulu were noticeably better (although they both seem to come from a similar design source), but according to this review they're on a similar level with some pros and cons in each brand.
