To each, his own.
For me, I'm in a phase where I love to try to reproduce certain beers. I've done several beers from CYBI podcasts and have been very impressed with the results. Living on the East Coast, I'm not able to buy some of the west coast beers I've enjoyed, such as: Deschutes Mirror Pond & Black Butte Porter or Firestone Walker's Union Jack & Pale 31, Pizza Port's Shark Bite Red. It allows me to focus on my process, remove variation and improve repeatability while producing delicious beer from proven recipes.
Maybe when I'm done having fun with other people's recipes, I'll focus on the creativity of recipe formulation. Then again, maybe not.
