Heya Mark,
A press with a floating platen shouldn't have any trouble with a hoodie. The upper floating platen is designed for use with items like that. (Just get something to raise the imprint area above the seams/zippers.)
My impression was, if you are working with vinyl, and you have the room for it, the swingman might be nice to give you the room to line up your work without the upper platen in your way and heat on ya.
A press is a press is a press, so I hear again and again, when one is comparing names like the ones you mention. It may come down more to budget, your preference for a swing or clamshell, and what bells and whistles. Good luck to you, and you know I mean it!
