If you are used to the terrain at Snowbird and Alta, the high alpine bowls at Breck will be the closest thing. The Horseshoe, Cucumber and Contest bowls off of the t bar on peak 8 offer the best lift served skiing on the mountain, if you are looking for steeper wide open bowl skiing. The Imperial bowl and Peak 7 bowl, as well as the chutes at the top of peak 9 require a 30 minute hike from the top of the lifts, but offer great skiing, although it is sometimes awfully windy along the ridge. The climb discourages many, so there is often untracked snow up there. There is also good black terrain off of lift 6, but the cover has not been great this year, due to the worse than average snow pack.
The blue terrain is, I think, very generously rated- the blues at Breck would be greens at Snowbird, but there are some nice cruisers all over tha mountain.
Snowpack this year has not been great (a problem common to most of the intermountain west), but I was up on Monday this past week and there was a foot of fresh in the Peak 8 bowls. They tend to get more snow than many areas of Breck because of wind loading.
