I made this exact same decision. I listened to the Dutch & Dutch next to the Mesanovics. But the room was so terrible, I couldn't really make an informed decision. I will say that the Dutch & Dutch could fill the room with bass with no problem and it was a huge room (warehouse, actually). The Mesanovic was the smallest of the 3 and I really wanted to get those. In the end, I opted for the Genelec 8361 without listening to them because of the GLM flexibility to adjust to my room (vs. Mesanovic) and because I thought Genelec would have better support and reliability, and would be easier to resell in the future. I didn't see any benefit to the extra cost of the Dutch & Dutch, and I was bothered by the fact that they still don't have the promised Room support. Having listened to them all, I think it comes down to these sorts of factors and not sound quality. They are all great speakers. It is more about the look, placement flexibility, warranty, cost, etc.
I will say that my wife hates the 8361s in terms of looks.
I will also add that I like the GGNTKT concept a lot, both the M1 and the M3. I am keeping an eye on those.
