Whats a good brand for snowboard boots?

DC, Nike, burton, ride, thirty two, salomon, and some vans boots - all reputable boot brands. The most important thing you do though is to TRY THEM ON before you buy them. Most likely your boot size is going to be different from your shoe size (usually smaller) and most boots from different companies do not share the same fit for each size (some same companies different models as well). For example my ride boots are 0.5 (U.S.) bigger than my salomon boots. And I tried on at least 3 different sizes of each boot I ever purchased. The most important thing between boots, board, and bindings is your boots. If they're too big or uncomfortably small your riding is going to suck or be painful even if you're on the perfect board. Some liners in certain boots can be heat molded at a shop for better fit. They also sell footbeds to make boots fit better by slightly raising your foot and making the boot feel a little more snug.

Vans, DC, and 32 are at the top of my list. Very comfortable and their reduced footprint tech is also helpful for larger boot sizes. Wore Vans Matlock boots (2010) last season and was very impressed with the comfort level. Their mid flex was perfect for the entire mountain too.
