The good folks over at Wordstream have come up with a nice list of Top 20 most expensive keyword categories in Google Adwords. Now, since a significant portion of Adwords ads are displayed in the search network, it is logical to assume that the same keyword categories (aka niches) would be good for Adsense sites as well.
