My Imperial Oaked Porter is my favorite right now for homebrew. Had the last bottle of my IPA (second batch of beer I made) last night and it was also delicious. I also loved the dunkelweizen I made about 4 months ago.
For commercial stuff...wow...so many styles to enjoy. For drinkability I love Pilsener Urquell. Zatec Dark Lager tastes like freakin' candy and I can quaff liters of the stuff. Hofbrau Dunkel is the same way. I also love Shiner Bock for a domestic brew. The caramel and spicy hop finish are second to none. And there sure isn't anything I can find wrong with a Paulaner Salvator (double bock).
I was drinking weyerbacher I think it was a russian imperial stout then switched to cerveza presidente that our suppliers brought north to the BBQ, ended up with some landshark then back to the stout with a special issue full strength padron rolled for the BBQ that smoked very well with the stout.
