I have the Baader-Zeiss BBHS prism (T2) and it is exceptional. I only use 1.25" EP's so don't feel the need to get a 2" diagonal, though if I did it'd probably be the Tak 2" mirror or the Sitall.
I definitely can see more detail in the BBHS prism compared to a friend's Tak mirror, though I am sure his astigmatic eyes disagree
