Any insights who have given online exam.
I think the correct answer here is that you should take both!
Although the GMAT Online is risk-free (other than the $200), since the scores live on a separate portion of your mba.com account, and because b-schools will thus only see the scores you choose to send, there are additional challenges inherent to the online, at-home exam--mostly internet connection issues, proctor delays (in many cases the exam takes up to an hour or more to begin), unexplained reschedules, confusing, contradictory emails from GMAC customer service, the lack of an ESR (Enhanced Score Report) option to review your performance, and misinformed / overly strict exam proctors (my first attempt was cancelled due to my "looking off screen" before the test even began).
If you do choose to take the GMAT Online, then be prepared to wait an hour or more for your proctor to start your exam, and try your best to have a fast, reliable, preferably wired (ethernet) internet connection, as well as a relatively quiet, air-conditioned space where you can take the test with minimal disruption. Purchase a modest-sized whiteboard, dry-erase markers with ultra-fine tips, and a block eraser. Don't over-hydrate, because you have to be on-camera for the entire test, and
you can't leave your seat at all during the (short) breaks. Don't look off screen, either! Close your eyes if you need to, but whatever you do,
don't look off screen; trust me--I learned it the hard way. Unlike the test-center GMAT, on the GMAT Online you can't select your section order, either: you must complete the exam in the fixed order Quant / Verbal / IR (but one benefit is that you get to skip the AWA).
If you live alone in a quiet, air-conditioned house or apartment with reliable electricity and internet, then you should be just fine giving the GMAT Online a try. For example, I live in a single-family home (3 kids, two dogs and my lovely wife), and it can be a challenge to find quiet time, especially with an energetic 2 year-old living in the house, so I had to take the exam late at night and hope for the best. These are the types of challenges that don't arise on the test-center exam, where having a stable, uninterrupted internet connection doesn't matter, the testing centers are usually comfortable and quiet, and your exam will almost always start on time.
Also, be prepared to wait up to 20 business days after the exam for your score to arrive in your mba.com account (in most cases, 2-7 business days), whereas the test-center exam provides you with your "unofficial" total score (Quant/Verbal/Composite) immediately.
Did GMAC change its policy? Because I have heard from others' experience that you can leave during 5-min break, if you show the proctor clean whiteboard.
