Sortable has wrong info on these cameras. Both have image stabilization to help with the camera shakes. Both have same sensor size.
ZR200 is the replacement model for ZR100. It has few more tricks than ZR100 but may not be worth more money. Currently, R100 can be had for about $60 cheaper.
Higher MP on small sensors may not be advantageous. Hence, ZR100 may even be better in low light. Both have fast shutter action for both still and videos. They are niche market cameras with specialization in ultra-high speed video.
