Mobile car detailing vs. traditional detailing shops — which do you prefer and why?

I’ve been going back and forth on this for a while and I’m curious how others feel. Do you prefer mobile car detailing or going to a traditional detailing shop? I used shops for years, but lately I’m wondering if the convenience of mobile services really holds up in terms of quality. My interior takes a beating from winter boots, coffee spills, and dog hair, so I care more about results than speed. Would love to hear real experiences, good or bad.
