The 'better' of the good sounds is not going to be found inside a computer program (like Audition). If they both sound good but have been captured with different placements, then your problem is just about conforming to a placement style.
Choose the lavalier for a more crisp, corporate but less naturalistic feel. If you can understand the dialogue as such, who cares about how natural it is? The product voice is promotional or for entertainment, both for which the sound source is isolated.
Or go with the boom mic / NTG3 to capture more of the environment, as you will surely here some audible reflections and reverb from the room that bring the viewer into the scene, but on a more down to earth level (not hyper-real or exaggerated). Provided that the mic is positioned correctly, the perspective of the camera is more likely to match, given that the mic is directional.
For video interviews I would be inclined to use the Lav mic and get accustomed to it and develop taste for it, but the choice is entirely up to you.
