Yep, this has been discussed many times. Comes down to personal preference. Some like it others don't. Familiarity with the coach, etc.

I'm with you though. Doesn't matter if I've coached with them, my kids went to school with them their entire lives, or their my neighbor. When I step on the court, I prefer to call them coach and not use their first name.

I was also taught to introduce myself and my partner to the players and coaches as Mr. and not use first names. JMO......you'll certainly get others.
