3) I will have more enjoyment looking at Deep Space objects, and not
trying to track Mars or other quickly moving objects.

Mars moves about as fast as all objects in the sky. really.

Yes; the earth's rotation is responsible for by far the greatest
portion of 'field drift': no celestial body changes its hour angle
anywhere near as fast as one degree every four minutes. Moreover a
solar system body with "direct" apparent motion will drift a little
less than the background stars, so although the Moon is the
fastest-moving object its apparent motion is always counter to the
earth's, making its drift rate about 3% less than a background
star's. Mars's apparent motion is currently "retrograde", but even so
it will take only a fraction of a percent less time to cross a given
field of view than would a DSO.
