4 years ago I switched from a nice tricked out GI contractor saw to a nice tricked out hybrid, and found there to be several advantages with the hybrid. It's not night and day, but since you're buying new, there's not much to be gained by buying the 60 year design of the contractor saw with the motor hanging out the back. Last year I upgraded from the hybrid to a 3hp cabinet saw...the hybrid offers more of the benefits of a cabinet saw than a contractor saw.
With the hybrid you'll get better dust collection, smaller footprint, a shorter drive belt (less vibration and more efficient power transfer), more mass, no lifting hazard from the motor, and in this specific case the trunnion design is better on the G0478 than with the G0444Z. If you don't need the portability of a jobsite saw, the hybrid/cabinet saw design offers the most advantages over a contractor saw or jobsite saw.
If you need to have a portable saw for occasional use, I'd just pick up an inexpensive separate saw as opposed to giving up the benefits of a full size saw for your main shop.
