X11's are utter ****e.
I did play around with a few of the other types but came back to DC H10-13X.
I will agree that some of the others beat them slightly in performance but...
You can tweak and fix DC's when things get slack.
You can get spares world wide locally eg gel seals, mic socks etc.
They work exceptionally well as a passive headset if you have the ANRs and bat runs out.
And another huge factor is that Headset Services do such a cracking customer support in the UK. There is no mucking around, you get to speak to the bloke thats going to fix it. The 2 times in 10 years I have sent stuff in it has always been turned round quickly with the minimum of fuss and came back as good as new for a very reasonable price. I might add both times it wasn't a DC failure it was me being stupid that caused them to need fixed.
