Most of the ceiling in my basement is 9'. I have soffits around the perimeter of the main room for the hvac/plumbing. I think it looks great. The high ceiling changes the feel of the rooms. It doesn't feel like a basement.

Any drop ceiling basement, says, "this is a basement."
Install drywall on the ceiling if you do not want a basement look. Everyone tried to convince me that I needed access, wrong! After 15 years, I have had no reason to access my sheetrock ceiling. I measured where everything was located in case the need did arise.

Does it look good?

It depends on the proportions and the window size and placement. Narrow high-ceilinged rooms with typical basement sliders at the very top can make you feel like you've fallen down a well.

On the other hand, a double glass door or larger walkout to a below-grade patio can open up the space to the outside in an inviting way.
