OpenSMTPd - is it time to move?

I wouldn't suggest moving sendmail from base, but I've noticed OpenSMTPd 
is gaining popularity.

I've invested 35 years in learning how to make sendmail work, so I can 
cope with it's convoluted configuration; although every time I need to 
make a change I still get twitchy. I've tried Exim and Postfix at times, 
but always returned to the devil I knew best.

What are people's real world experiences with OpenSMTPd for a low volume 
MTA? It's not like we need UUCP or Mail-11 interoperability any more.

Thanks, Frank.
