I have some styles that I like to tinker with and others that I have locked down. I have one clone that I have left as designed by the brewer, Pateros Creek Old Town Kolsch, just because that beer is perfect and they no longer distribute it. Others I have tweaked to the point that I am satisfied that it's a great beer and really really enjoy it as is. Hoppy beers get tweaked a lot because I like seeing what different hop and specialty grains bring to the table. I also haven't found the perfect brown/Stout/porter but that's mainly because I don't gravitate to those styles so they don't get brewed often.
As for commercial, I usually grab new stuff, always on the lookout for something new I can try to incorporate into a brew. However on the odd chance all my taps are dry I'll head to one of my old time favorites to hold me over.
