Since the largest resolution "natively handled" by PD is 1920x1080 at both timeline and production levels, I take the view that I would prefer to be more in control of manipulating my hi-res images than less. I have, in the past, had cause to doubt PD's image handling processes, as they are internal to PD.
The editing of images in PD is serviceable but basic, with little user control, and therefore I prefer to manipulate my images in photoshop or similar, resize them properly to 1920x1080 and import to PD.
