Well, I've done what a lot of folks have done, started with one form of extract, hybrids and gone on to full on all grain brewing.
I've had some spectacular failures all along the line. I stick with all grain brewing now because I think of it like the difference of making a boxed dinner (Hamburger/tuna helper or ramen) vs making from scratch. There is a time and place for it but the difference in time for me of extract variants vs all grain variants is not that much the way I do things. It is one thing for me to come home from work and not have the time to make a full on meal every night so the boxed dinners is the way it goes. I don't have a lot of time to brew. Sometimes I get three or four brew days in a month. Other times it may be 6 to 8 weeks between brew days. Still I would rather brew something I can control as much as possible even including the set up and clean up. (Let me tell you something, trying to brew when it is single degrees outside is a challenge..) I also like generally the process of everything quite a lot till comes time for clean up and the wort chilling process. For some reason those two are always a pain to me, and that will not change no matter what brewing process I use. I don't mind extract brews but I feel that the time change is not that much greater on the back end, if I want to do it I want the whole experience. No problems with anyone that does it their own way. What folks enjoy is what they enjoy, that is all that matters.
