The Pearl uses SXRD technology (LCOS). It has three panels (R,G,B), so has no color wheel and therefore no rainbow effect issues that might affect some. Being LCOS, it also has an essentially invisible pixel structure, so no Screen Door Effect. Sort of a projector for everyone.
Watching the Sony is extremely enjoyable.
Mitsubishi HC5000 LCD home theater projector
It was a tough call, between this and the Panasonic PT-AE1000U. The Mitsubishi's strengths, include unmatched sharpness, and out of the box excellent performance. Being a typical LCD projector, pixels are just barely visible, in large bright stationary areas, or things like white movie credits on dark backgrounds, if you like to sit close. In all fairness, though, pixels are still a touch less visible than with a 720p DLP projector.
The image below is from "Starship Troopers" (standard DVD).
Erogonomically the Mitsubishi HC5000 is tough to beat - a wide range zoom lens, lens shift, and by far the quietest 1080p projector on the market, in fact so quiet, that it is probably quieter in "full power" (bright lamp) mode, than any of the other projectors in their low power (economy lamp) modes. In low power, it is for all practical purposes, silent.
