Definitely the 16" Teeter. Any night that is worthy of spending quality time is worthy of a one-hour drive for darker skies and longer looks. Grab and go for me is the 25x100's. Those are just fun and casual.
I am partial to the 71" focal length on the Teeter. It is easier to use with my 6'3" frame when standing, and the views are great. Of course, the motions are smooth and agreeable. The 8" SCT is difficult to contort myself when using the finderscope, and I'm a star-hopper - not a button-masher.
