Alrighty, I lived in Gunnison for the last 4 years and these are observations of CB. Correct me if needed Sac...
Steeps: The reason you go to Crested Butte. This past winter was epic, record snowfall and really well bonded snow (well, most of the season). Places like Teocalli Bowl, Third Bowl, Funnel, Spellbound/Phoenix Bowls...so good. Just be prepared to wrestle for lines with locals. When snowfall is abundant, no better skiing in Colorado (save for a few BC areas). That is just it though, when snow is not in abundance it gets pretty lame.
Park/Pipe: This is a Jekyll/Hyde situation here. The pipe this year was amazing, the first cut was excellent and was maintained well throughout the season. It is short though (4 medium/big hits tops), super fun though. Which what is kinda weird because the park was awful, except for the last day of the season...once again, weird. No big jumps, no innovative rail set ups, and the lips of the jumps were just simply too much (sometimes literally steeper than the landings).
It just depends what you want to do, you will not become a park star at CB. You will be a better skier though, it is crazy how good some of the locals are...and many unsponsored.
