Tuning pianos, like every fine skill, is a skill that requires both knowledge AND practice. Some people study hard and practice more under the supervision, critique, and feedback of top technicians. Others don't put as much study or practice into their craft before they start offering their services to the general public, i.e. to YOU. Consequently, they don't tune as finely as better tuners and they know it. It is reflected in their price. And ultimately, it is reflected in the sound of YOUR piano, YOUR playing, YOUR enjoyment and YOUR satisfaction while playing, and in YOUR motivation to play more and grow in your own skills as a piano player or performer.
