Camelback and Blue are very comparable in my experience. It has been a while since i have ridden Blue because I always felt Camelback's snow making/quality was better.
Both places are generally zoos on the weekend and quiet midweek. Camelback definitely gets more traffic on the easier terrain but if its totally open, the place does handle the amount of people it gets pretty well. They also have a separate lift for the terrain park.
My advice, as with all of the hills around these parts.. go early. Get out as soon as its open, take an early break and get back out when the masses stop for lunch. I don't really do the night thing anymore so can't speak to that.
