I know people are always trying to decide between these two, so last night I did a shootout in my home and with familiar material.
My RS1 has 700 hours, but is by all reports notably brighter than some others. The VW60 has 40 hours on it. Both were projecting onto a 125" grey screen from 15 feet.
The most obvious difference between them at first was that the RS1 was brighter. The VW60 needed to be in High mode to match the RS1 in Normal mode. However, both gave quite acceptable (to me) brightness on a screen that size even with the VW60 in Low.
That aside, it was really hard to pick a 'winner'. Black levels were very close, with the VW60 just a a bit better. Neither were as good in this area as I'd like. The RS1s added brightness and native contrast therefore gave the image a little more punch. But the emphasis is on 'little'.
The RS1's colours were more vivid, but the VW60 can be adjusted to give similar saturation. By the same token the VW60 was a tad more natural, especially using the Normal colorspace. Black Level uniformity was a little better on the Sony, and it didn't have any signs of colour uniformity. The only time I noticed Brightness Compression was with white type on black bcakgrounds.
Noise wasn't an issue with either, either auditory or in the image.
Both are big, dark and shiny.
So, to me, they are very very close. I even used masking to have them sharing the screen and found it pretty hard to separate them.
In the end, I may go for the Sony simply because it has the extras of powered lens, anamorphic capability and for the very slightly better blacks.
Then again, I may not.
