I'm on the side of the spectrum in that I have a burger pretty much everyday, a good substitute for breakfast I find.
Mind you it's one of the cheapest ones on offer at maccas, the double beef and bacon that used to cost only 3 bucks.
It sucks that since Feb I think of this year the tight arses now force you to buy a meal along with it, you can't buy it by 'itself' anymore. Bastards, business must be tough/slow for them to resort to these tactics.
Anyway I like because it feels me up pretty much for most of the day and being a relatively small burger it doesn't have the same amount of calories/kilojousles/what-have-you of the other 'proper' fattie more expensive burgers on the menu.
