A few years ago I used to own a Saxon dob, 8 inch f5. Whilst the views were nice enough a star test showed obvious spherical abberation. I have heard this is par for the course with this model.
On the other hand my GS dob showed an identical set of diffraction rings both sides of focus on a rare night of exceptionally good seeing. The GS mirror is way better !
Still I do miss the little 8inch f5 sometimes, as it takes up much less space than the 10 and could possibly travel with me on work trips.
