Hi Jacko,
No - I have only experience of Blue Vixen, APG-73 and APG-79. Discussing them at length with Typhoon drivers has led me to believe that the 79 is a far better system than Captor M. Same goes for the link fit.
You will see that I have never compared the two helmet mounted systems or heaters you mention - just stated that I’d be more than happy to fight pop ups with the JHMCS / 9X combo. Not sure how good the Typhoon helmet is - but I did hear that the guys didn’t like the weight and didn’t wear it for some sorties. Not something I encountered with JHMCS.
