Do you mean side-by-side or quickly blocking one and then the other, or taking some time between each? My memory is that when I compared my 8150 to my JVC years ago there was little CR difference for most scenes, so I looked for scenes where there were differences. With a little difficulty I found a scene where I thought the Planar's ANSI CR gave it a nice visual difference. I remember a black suit in the desert from one of the Bond movies.
I didn't find it difficult to find scenes where I thought the on/off CR advantage with the JVC was clear. The same thing with the Samsung 9000 that I had for a very short period before I compared it to a JVC and then sold the Samsung. I recall the differences there were pretty clear even in some indoor scenes in a Riddick movie that wouldn't be considered the darkest, but I don't recall if I tried that one with the Planar.
I've used the analogy before of 2 leather chairs where one has extremely soft leather, but a pin sticking up that you hit multiple times per day, versus another chair where the leather isn't quite as soft, but much less of a pin that bites every once in a while.
Bill Cushman pointed out years ago that even 30:1 ANSI CR would be fairly satisfying, but not having enough on/off CR means that the intra-image CRs sometimes drop very low and become very noticeable.
I think that for those with experience and paying a little bit of attention the low on/off CR can be like an alarm going off, where the lower ANSI CR of the JVCs is more like white noise that many people find they don't even notice without it being pointed out.
Maybe a little bit like fan noise with projectors where some of the biggest complaints are for models that have cycled their fan speeds based on what was necessary instead of keeping a constant speed, even if higher.
