A small refractor can't be beat for grab-n-go and potability and no cool down. But, here's the most important thing: the views are similar to your bino views. Somewhat better, and, more stable on a decent tripod. But about the same.
A eight inch DOB is a game changer.
I would argue that going from a small bino to a small refractor is almost no change --- why bother??? And it is most certainly not the "wow" experience of a "first" telescope. Consider too, the cost. TeleVue is really proud of their refractors. An 8 inch DOB is chump change in comparison.
Get the DOB. If you absolutely HATE it, get the small refractor.
