I work as a plumber
The majority of my customers spend somewhere in the ~$200-$300 range for kitchen and lavatory faucets, which is about the medium price range, with most of them being on the lower end of that range.
Do not buy the lowest end box store brands. Those are just horrible. They are difficult to repair, sometimes impossible to repair since you can't source parts easily enough to make repairing it worth it, and many tend to start dripping within a year.
The only major thing that really changes when you go into the highest price range is the aesthetics and finishes of the fixtures. The majority of the $500+ fixtures still use the same internal parts as the $300 range fixtures.
As far as brands go, I usually recommend Moen, Delta, and Kholer.
Delta faucets tend to be the easiest to work on, even for a DIYer, and their parts are easy to get locally for most locations. Kholer and Moen parts can sometimes be harder to source locally for some areas.
Moen and Kholer tend to be more expensive, but they do tend to last longer before needing repairs.
As said above, the biggest difference in the prices comes form the style and finish. Polished chrome finishes tend to be the most inexpensive and they are by far the most common. The finish makes no difference other than matching the rest of your bathroom. No one finish lasts longer than the others in my experience. They all tarnish and discolor over a long enough time line.
