You really need to try them
If weight is an issue for you then do be aware that the "lightweight" badge on the Darkglass cabs is rather disappointing - a lot heavier than their rivals. Some of them are still heavier than the old Marshall VBC412 cabs I used to use 20 years ago.
I have 12 inch and 10 inch based cabs from Barefaced and they are VERY different in tone. I like them both and I'm still in the honeymoon period for the 12 (Super Twin)
My thoughts though, after playing alone and with backing tracks / CDs etc is that when playing alone without any other noise at all I probably (it's very marginal) prefer the 10 inch cabs. But when other stuff is going on I definitely prefer the 12.
My Super Twin is very new though and it hasn't loosened up yet so my views may well change.
In the past I owned a pair of Mark Bass 1x12 cabs and they had a very warm sound that when paired with a MB head as well didn't cut enough for me. I sold them went with Berg HD112, then to Berg CN112 (didn't like them but a lot lighter than the HD112) then Barefaced One10 (pair - kept them) and the BF Super Twin. Before the Mark Bass 1x12 I was using a pair of the massive Marshall VBC412.
The Mark Bass cabs were the least impressive of all of those. But I don't know what music you play - they might be perfect for your needs - and also the newer model 2x12 might be quite different to the older ones. I don't know.
