In general, we choose not to publish such comparisons as any comparison produced by a software company will naturally be biased. In the end, we hope that our end-users take some time to download our evaluation version and make a decision appropriate to their needs.
I would like just to note that TestComplete won the Jolt 2008 Productivity Award in the Testing Tools category in the 18th annual Software Development Jolt Awards presented by Software Development magazine. As you know, the JOLT Awards is not a popularity contest - a panel of industry experts actually examines each product and passes judgement.
I recommend that you see the "Getting Started" section of TestComplete's Help system. A printable version of this section (Getting Started With TestComplete 7.doc) is located in the "<TestComplete 7>\Help" folder.
