Welcome Luke!
The 2 scopes you mention are quite different in what they'll show you and how it will be presented. What sort of objects are you interested in looking at? And for AP?
The refractor should no doubt give you fine views, and a relatively wide field of view compared to a large SCT, but a larger aperture scope will have much greater light grasp. You'd probably need to be using a similar mount for both scopes, so the portability thing will likely be marginal...one is a long thin tube while the other is short and dumpy
Have you ruled out a reflector/Dobsonian? You could probably buy quite a substantial setup if your budget stretches up to a large SCT and mount.
