Having decent image stabilisation is a must for any video production especially for those who prefer to shoot without the use of a tripod (I'm guilty). Certainly, scenes can be post-processed in applications like Final Cut Pro X or Premiere etc to remove or at least reduce any visible shake but its at the cost of some cropping to the scene.
Both camcorders also offer improvements in shooting under low lighting conditions. I'll write more about the feature sets of these camcorders at a later date at realworldimages.co.uk. EA
