When I purchased my first pair or Wilsons, I compared the Sophias (first version) to the WP 6s which I could have purchased for a few thousand more as they were being phased out for the WP 7. I went with the Sophias because I felt that they were more musical and less clinical than the WP 6s. The WP 6s did have better articulation, extension, imaging, soudstaging, etc.
When I heard the WP 7s, I just had to trade up. The WP 7s had the musicality of the Sophias plus the soundstaging, imaging and other attributes of the WP series.
I now have Sashas which I love as they have even more musicality than the WP 7s.
In short, I felt then and now that the WP 7s were the first speaker in the WP series that did not lean too much to the clinical side. I'd go Sophia 2 which I thought was a natural successor to the original. Of course, if you could stretch for WP 7, the gains are huge in every way. Just my humble opinion.
