I produced a TV pilot in 2006. We shot it with three HVX200s with matte boxes, follow focuses and filters along with microwave video transmitters and we used the DV Rig Pro. They worked very well, you can read all about them and see images of my camera operators using them here http://www.kenstone.net/fcp_homepage/tv_pilot_hvx_200_brockett.html Scroll down to see pictures of the rigs.
The Fig Rig is something completely different. Personally, I don't like the Fig Rig, it requires you to suspend a fairly heavy object away from your body. It is like a Steadicam, it works well but it is fatiguing to use continuously.
The DV Rig Pro has a suspension rod that fits into a belt pouch that the operator wears, putting the weight of the camera package on your waist and hips as well as your shoulder. Our operators shot handheld (with the DV Rig Pros) for about 10 hours a day with no major fatigue issues. Highly recommended for any kinds of handheld shows.
Multirig won't give you steadicam type float - if that's what you mean by fluid - figrig can if you practice. What I don't like about either of those units is that they take your hands off the controls.
True pwyll, the DV Rig Pro is for allowing you to just shoot relatively steady footage for long periods of time, definitely no substitute for a Steadicam. Most of the shots we did were basically with the camera operators standing in one spot. I grilled the director that if we weren't going to be moving around the cameras a lot, why not allow the ops to shoot off of sticks with a loose head but she insisted on everything being shot handheld, which seemed pointless to me.
The FigRig doesn't really give that floating Steadicam look either, I agree. If you want the Steadicam look, use a Steadicam.
