Snowboard boots are not meant for strutting around at the base of the village pretending to be a snowboarder. I would recommend you buy boots that are good for snowboarding and less based on appearance (color) and "walkability" like Lil Wayne here...
I like very stiff boots, because I want to feel everything happening under my foot. That said, to the OP, the best boots you can buy are the ones that fit you the best... If a traditional lace boot with a flex rating of 4 fits you better than some 8 rated dual boa boots, you will ride better in them.
Try on everything! When they fit right you'll know it. I can leave my boots barely snug and there's very little foot movement.
