I was in the same spot 2 weeks ago, after several hours on the net and visits to about a dozen sporting goods stores I heeded the advise of many of our fellow campfire members and went with Camera Land and chose a pair of Minox BV in 8X42.
That being said I did handle the 8X42 Arcadias, and 6X30 Yosemets as well, and the 8X42 Redfield rebels. If your dead set on only one of the two I would say the glass is compareable, I liked the ergonomics of the Redfields a bit better however they are heavier than the leupolds. One of the things that turned me away from the Leupold Green Rings was that they are not covered by the lifetime unconditional warranty. I think that the cammo Arcadias are cool and might have gone with them just for that.
