What are good beginner snowboard boots?

I have a burton 08 blunt and burton custom bindings. I've tried some boots on and I really like the BOA system. Some of the boots I'm looking at are the 32 stw boa and the k2 raider boa. It's my 3rd season snowboarding, I spend most of the time on the groomers and in the intermediate/beginners park. Any ideas on whether or not these boots are good and if not what is?
