Is San Francisco a Good Font?

i was going to change my custom font for stem font, but san francisco as a base font is a little boring. I wanted all the benefits of the system fonts, and so i switched it to s f rounded. The only negativety i've gotten was a combination of people who don't like change at all. It's been mostly unchanged since overcast one point o ind 20 14. But now they have this pill shape on the playles that makes everything bigger.
