In my experience, the biggest difference between I and P is that I will in many cases give you judder.

The uneven distribution of fields in the Interlaced technology. You'll notice this especially with slow panning shots in a movie. In the form of an image stutter which can be quite annoying.

Especially the pioneers have a great way of dealing with this in advanced cinema mode, which will give you judder free pictures while being interlaced.

I've got a toshiba hd-e1(1080 I) and a gen. 6 pioneer plasma. Great picture without judder.
