Here's the first significant difference. While the PT-AE2000U has very reasonable sharpness, it is among the softer looking of the 1080p projectors. This is due to Panasonic's SmoothScreen technology. SmoothScreen makes the pixel structure of the LCD panels virtually invisible. Now, in my opinion, that is a good thing, but hardly critical for 1080p projectors. I say that, because most folks at normal seating distances, really can't see the pixel structure either way. That's markedly different than 720p projectors where some sit further back, just to avoid seeing the pixel structure and screen door effect, and others favor DLP projectors for the same reason (less visible pixel structure).
