Try Electronic Design News and Embedded System Design -- both of these have had comparison tables in the past.
In the end I've found that these tables are only good for getting into a very wide ballpark -- you've still got to dig through all possible vendors looking in detail at their data sheets.

Agreed, about the work. There is no avoiding it. Comparison sheets can provide the general family (which, based on other experience or criteria, may be an important selection criterion; the amount of flash and ram (the application may suggest something here); the vague number of serial ports, A/D and D/A converters, power supply needs, and a few other basic things. But known application requirements usually have at least some very precise elements and those are as important in selecting a device as some of the less precise ones (such as what the code space and ram space requirements may be for a new project.) But, I suppose, if you don't really have an application and are just wanting to daydream about where "things are at, today" then a table might be good.
