Yes, one has to go for the micro rotor, there is no question about it! I went for the sport auto because of the versatility and because it has the best bracelet that I have seen. But the finishing on the original movement is unbeatable. The comparisons with Dufour and Kari are not exaggerations, it is in that category.
I have also seen the black opaline dial in person (the classic) and it is absolutely stunning. And indeed impossible to photograph! 
I think you will enjoy this one for a long time ...
