PeaceInOurTime,
Those are very nice comparable multitools that you've mentioned. I can see how they might easily be a good substitute for the Juice Pro or XE6.
I can't post comparison pics, but I can give you comparative dimensions:
Juice Pro/XE6:
length - 3.25"
weight - 6.7 oz.
Sidekick:
length - 3.8"
weight - 6.9 oz.
Wingman:
length - 3.8"
weight - 6.9 oz.
Rev:
length - 3.8"
weight - 5.9 oz.
The juice is the most compact by a half inch which, to some, is significant. And still quite light. Speaking for myself, I love the solid feel of the Juice Pro. It's like a solid piece of steel or, better yet, like a roll of quarters holding it in my hand. Very comfortable with no sharp edges. Not to say that the Wingman, Sidekick, and Rev aren't very appealing. I wouldn't feel shortchanged by any of them. Still, I'm sorry to see the Juice XE6 go.
