We looked at the Zund, Kongsberg, Multicam, and took a quick glance at the Summa. Problem with that one is simply size. It's small--can't cut a 48x96 board. Totally out of the question for us or any other shop looking to do any real work.
The Multicam is okay, but I think they've got a long way to go to be on the same level as a Zund. Much slower machine, very new to the "finishing" side of things. They make a heck of a router, but are lacking on the digital die end of things.
Kongsberg is much more comparable, but pretty much the same price. If you're going to pay the same money, why not get the best?
So far, we've had it up for two days. Done a bunch of one-off cuts to learn the bits/blades including high speed foamcore (at 40 inches per second!), gator, kiss cut vinyl, thru cut vinyl. Also have run about 40 sheets of coro and 200 sheets of styrene through it. Also routed a few sheets of MDO and acrylic (1/8" and 1/2"). The finished edge is absolutely beautiful.
