The Custom is a good overall board, I've had one for a couple years now, although it has been demoted to low coverage and rock duty for next season. Don't listen to all the Burton haters that will tell you everything they make is crap. To each his own though.
The bindings all depend on what type of riding you do. I've owned Customs, Missions, Cartels, and Co2s. I loved the feel of the Cartels, they were responsive, yet playful. Not the highest quality though, I broke two ratchets last season. I've only ridden my Co2s a handful of times (on my pow board). Super stiff, responsive, and comfy.
