Thanks for asking !
I'm not going through the 63 other answers, comments, and rants. Much has probably been said and argued already. So I'll restrict myself to a few essential thoughts.
So if you're a photographer whose photos are good enough to serve as the required end result, then JPEG is just fine.
Maybe the new HEIF format might turn out a better alternative to JPEG (and many other formats), but it isn't a commonly accepted standard, yet.
