Ask two questions:
How portable do you want your "one" scope?
How important is a long or short focal length to you?
I had to try to work out the "one scope" question myself... I ended up with a SCT on a eq mount in an effort to compromise on all fronts. There won't be a simple answer to your question. Just try to work out answers to the above questions and remember the most used scope is the best scope. Aperture/size doesn't rule if it stays unused...
