I wore a full beard for 17 yrs. then cut it off for the last 9. I prefer a beard but its hot in summer.
As I really hate to shave, I'd prefer a beard and have had one many times over the years.. these days it's so grey, it doesn't look as good IMO.
I hate shaving, so I always use beard trimmer I hate maintenance, so I trim my beard only once in a week or so
