Snark aside, I have a personal office and I love it. I don't like to listen to constant noise/music to cancel out the other noise/music. I like being able to have private calls without all of the noise in the background. If I'm working on something particularly difficult I like closing my door and having peace and quiet. I also enjoy the sense of ownership and prestige. It's nice feeling like I matter and my space and attention are worth something.
Working in an open office is too chaotic for me. Being around people is exhausting and distracting. I like to have a space I can retreat to for a few hours and get some deep work done. Silence is usually what I appreciate the most.
