Design of the Trotec forces the smoke near and on the lens and the surface of the substrate. The Universal does not appear to suffer from this, they have more suction (2 x 4" ports vs a single 4" and one 2" on the Trotec) and you can divert the air suction more heavily to the bottom which gives you a cleaner cut and less mess on the top of the substrate. This is all theory of course as I don't have a Universal, but examining their downdraft table vs the Trotec's I was very impressed, and I was also impressed with the extra features their software had.
