Burton - Let's face it, these guys are the originals. I use Burton Driver X boots
Nidecker - I have a Megalight board from them. It's absolutely the best board I've ever ridden - unbelievable. The only down-side to it is that it has a pretty soft "Gallium Elektra" base, so don't take it out early or late season or you'll be hosed...
Rossignol - I started snowboarding on a Rossi Strato, and it's still my favorite board - it's just a well made, lovely long stiff board. Great for backcountry and carving... I also used to ride using a pair of Rossi boots with their 'SIS' step-in system, and I think it's so much better than either Clicker or Switch. At any rate, I can click in and go faster than any of my friends who are using either of those... ;)
