Is meat from butchers better?

I am trying to get into this healthy eating thing as i am trying to shift a small spare tyre around my waste…I get plenty of excersize but I have started to pay more attention to food…meat from the supermarket is cheap but is it decent…should I be worried about growth hormones and additives? and if so would meat from a butcher be of a better quality and maybe cheaper? Is organic meat worth the price tag?
