I dont think in a large tank it will be noticable. The Vortech's have a wider flow it seems (less of a beam), but a prop pump is a prop pump, you know? In the end, what varies is how the outlet/intake guard piece directs the flow. I just swapped out the guards on my 6100's for the guards on the 6200's and the flow spread out into more of a cone, or wall than the previous beam.

The thing is, on a large tank like you are planning, I dont think you will notice the difference, and if anything, having a 5000+gph tunze will do more for you than a 3000gph Vortech. In a larger tank, with the way flow diffuses, and with multiple pumps, the differences will be subtle at best.

Its all in the outlets anyways. I know people that dremel off the 'cylinder' on the outlet of their tunzes and the flow turns into the same thing as a Vortech.
