In this newly updated FAQ I'll attempt to answer those questions as well as possible, incorporating my first-hand knowledge in reviewing numerous 2010 3D TVs, conversations I've had with industry experts...
...Viewing certain programming on a 3D TV can cause headaches or other ill effects in some viewers, especially over longer periods of time. In our experience, and in the opinions of most experts we've consulted, the main cause of headaches or eye fatigue isn't the 3D technology itself; it's badly produced 3D content.
Comfort is a major concern of most 3D producers. Too much of a 3D effect can become tiresome after a while, abrupt camera movement can be disorienting, and certain onscreen objects can appear blurry, for example. The best 3D movies, like "Avatar," tend to use depth effects that stay close to the plane of the screen, with fewer gotcha objects that pop out or recede into the screen excessively.
...We consider "good" 3D content (think "Avatar") the most important factor in whether 3D is enjoyable to any given individual.

3D similarly needs to advance beyond the gimmick stage. "We need to move beyond jutting objects off the screen at the audience and use depth as a natural component of the world on screen,"
and another: http://www.gamesindustry.biz/articles/digitalfoundry-stereo-3d-year-one
it's all about generating depth, whereas the "in your face" potential of 3D that springs out of the screen is rarely explored at all. The illusion fails when the screen doesn't occupy most of your field of view.
Effects that "pop out" of the screen are generally dismissed as being gimmicks or party pieces
All that being said, there is still content out there that exploits the pop-out side of 3D. The content makers decide on the amount of depth when they make the content (usually by setting the distance between the lenses of the right and left cameras).
Using either passive or active 3D, there should be no difference in depth or pop-out.Edited by Augerhandle - 8/11/12 at 5:50pm
