Hi Buster,
It really depends what type of beer you like. There are plenty of brands out there and most will produce good beer.
Probably more important than the brand of kit is your brewing method, including things like sanitation, the ingredients you add to the can and the temperature at which the beer is fermented.
Check out
this thread for some thoughts from me and others about how to ensure your beers are the best they can be.
Cheers,
Oliver
