From Art's review dating back to 2008:
"The JVC RS1 until just a couple of months ago, has been the generally considered best overall 1080p projector selling for under $10,000. Even with the price drop to $5295, most people will have a hard time justifying the extra $1500+ over the Epson. That said, the JVC, I think, is still the better projector, despite the slightly softer image sharpness. It has a slight advantage in both shadow detail and black levels, and is almost perfect out of the box. I'll still consider it a step of from the Epson, but, the Epson is the better value proposition. Those really into the last ounce or two of performance will still want the JVC, and can easily justify the price difference. The JVC will also appeal to those with larger screens. Ultimately it is still much brighter in best mode than the Epson."
The HD250 is essentially an updated RS1 at 1/2 the price. If movie viewing is your main objective, then you'll be surprise how contrast will impact depth and detail. The RS20 will blow the 1080ub out of the water, but then the price is almost 3x, so it's not fair to compare.
You may also consider the Sony SXRD/LCoS series for movie/sports experience.
I'm sensitive to RBE, so I cannot comment on the BenQ.
