I thought it was a load of BS that a person could taste the difference between all-grain and extract beer. Boy was I wrong. I made the AHS Oktoberfest all-grain kit, and it's honestly the best beer i've ever tasted, ever. Fast fermentation (pumped out the water in the airlock), higher attenuation, and a relatively slow and simple process have me hooked.
My next question is as follows:
I'm aware of how much better pilsners, golden ales, etc are when doing all-grain. How much better are the all-grain imperial stouts, porters, etc?
