Between those two my pick would be Loveland. It is not on any mega pass deal and has fun terrain. So the amount of people that hit the Luv is much less In comparison. Plus it is probably the quickest Dtown drive to any area amd it's location lets you know when traffic is starting to suck and you can get out quickly if you want. Plenty of the type of terrain you want there too.
A-Basin is pretty rad. Smaller, though I don't know how much Montezuma bowl has expanded the terrain and feel of the place either. The season generally runs until June there instead of the first weekend of May like the Luv too.
