The Santel appears to be a fine instrument. A 6 inch of this quality for just over $1000 is a true bargain. It would be very close to owning a 6 inch corrected refractor at many times less the price. And it would be much easier to use.
I could go for that scope
Not the comparison you guys are discussing, but I had the chance to 'side by side' my 10 inch dob with a C9.25 at a start party 2 years ago. The views of everything, including Mars were almost, or even 'dang near' identical in our two scopes.
