It's been a little while since the Variety map pack was released. But are people satisfied with it? Do they feel it wasn't worth their $10? Chris Wilcox at www.thatvideogameblog.com takes a good analytic look at the maps, looking at aspects such as what game modes suit those maps.
He also says that these maps won't do well as replacements for the standard maps.

The new CoD4 Maps are out - and well abused at this point - but many people are feeling that they got less than their money’s worth. Only three of the four maps are currently in public rotation with the smallest map, Killhouse, rarely being seen outside of a private match here and there. The other three are (IMO) playable, but far from replacements for any of the standard maps. Here’s a quick rundown of my opinions of the three (check out Se’s look at the maps here).
