To answer the OP's question, I don't know I have a clear favorite. Wisconsin has so many craft beers to choose from it's hard to have a favorite. I just keep trying good beer after good beer.
Spotted Cow is not bad, for sure, but is viewed almost like Bud Light by the craft beer drinkers in Wisconsin. I swear it's more popular by people outside of Wisconsin than inside Wisconsin, though that's probably because it's so popular it's sold everywhere up here which means it can't be a hipster beer anymore.
I am just starting to get into homebrewing with kit beers and cider, and there's nothing like pulling a glass of something you made yourself out of a tap in your own house. I started with cider, and a 5 gallon keg lasted 3 days with a bunch of friends helping me build a fence. I've kegged an identical batch of cider, made and kegged an American Pale Wheat beer (extact kit) which just finished minus a few bottles I took out of the last of the keg. I've got a Summer Ale excact beer that's waiting to be kegged when we get home from our camping trip, and two more batches of cider aging in the basement.
I plan to get a few one gallon batches of cider going to try various yeasts and compare, and once the Summer Ale is kegged I've got an English Ale extract kit waiting to be brewed.
I suspect the number of commercial beers/ciders we buy will drastically drop as my homemade pipeline establishes a little more firmly.
