Ah, now you're shifting the goal posts around a bit
Using your own eyes there is a LOT a 4" or smaller high-end refractor can not show you. A big Dob will always show more, even in light-polluted skies. Plus, with the amount of light you gather using filters to mute the light pollution becomes very practical.
For imaging on the other hand, there is no doubt that even an 80mm refractor is extremely useful.
