Any comparison like that is obviously subjective. However I looked at the Orion nebula and in particular the trapezium at around the same power and with the same eyepieces with both scopes over several nights in each case. In France I was in an area with "the darkest skies in Europe" according to my host. Certainly mag 6 stars were easy naked eye. Seeing was steady: could see good detail on Jupiter.
However, my subjective impression was the view was a bit "soft": and I found it very difficult to see the "E" and "F" stars in the trapezium. When I came home I saw both in late twilight with Orion lower in the sky, from a city location looking across the city, and the seeing was not particularly great... maybe as someone said the smaller aperture can cut through seeing easier- but I looked on several nights in France, and had the same problems each time.
We are talking high end optics in both cases here, and the Tec is a wonderful scope, it obviously has a greater light grasp, 140mm vs 102mm: but to my surprise I felt no temptation to "upgrade". I like the sharp, tight stars and great contrast I consistently get in the Tak.
It would be great to do a "head to head" comparison, but I can at this stage only go by my subjective impressions.
Also wrt to the Williams: they can produce great scopes, but in my experience there are sometimes some quality control issues. I returned a Megrez 110 3 times with QC issues. Nice scopes for wide-field imaging.
