Shortly speaking,
Prism telescope has larger field of view and greater magnification, which 
permits a better control of the touch between two bodies.
The disadvantage is that it is substantially heavier and bulkier.

Both give you direct image.

From my experience the best is inverse image Kepler telescope which has all advantages of the prism
telescope, but is light and have wires in the field of view.
But the only modern sextant which is equipped with such a telescope is SNO.

Sextant Telescope

I would like to know your opinion about the advantage of using a Prism 
Telescope (7x35) compared to a Universal Telescope (3/4x40). Both have the 
right image, or is it inverted?

Thank you.
