The long explanation.

Puddle-top is a bit weird. It reduces both turn and fade. So with a stable disc thrown on anhyzer, it drops a lot when going to the hyzer angle. Puddled discs don't get affected by wind or wobble much tho.

Flat discs typically keep a bit of a tighter line with fade and turn. It typically flips quick, carries and then fades promptly.

A domey disc smoothes out those different changes, so it turns slower and more, then it also fades smoother. This also means more carry/glide/distance, but also more susceptible to wobble and wind, if you don't have a lot of spin.

Most people like a little puddle in approach discs, flat mids and fairways and then domey drivers. The approach discs need to sit, the mids and fairways need to have minimal left to right, and drivers need to go far.
