Data seems to suggest that on average PS3 owners and 360 owners buy about the same amount of games per user per year. Microsoft's hype with regard to attach rates compared to the PS3 isn't very useful for comparison purposes as the 360 had a 1 year or more headstart, also if your console sells more in recent time this should drag down the average attach rate comparatively for such a console as the average new user will not buy as many games day 1 as a longer period average attach ratio per console. New users will expand their games library in course of time.
Below is a listing of both platforms top selling games (please politely correct any mistakes):

25) Crackdown
9 of the games are currently not available on the PS3.
* Notice regarding these 360 "exclusives" Gears of War, Call of Duty 2, Bioshock and Mass Effect are also available for Windows and BioShock is coming to the PS3. Although I counted Call of Duty 2 as a 360 exclusive it's old with COD3 and COD4 already on the market.
Conclusion: The PS3 has just as many top games as the 360 has, despite the 360's one year headstart. IMO 360 fans claiming the PS3 has no games should be left ignored.
