There is no undisputed 1911 king of the hill. For trigger quality I would single out Kimber (under $900) and DE 1911 (under $700). For sights, R1 Enhanced with factory fiber optics, and Kimber with fine Novaks. Thumb safeties, beavertails, serrations are best tried in person. Don't worry about MIM parts, their presence is no longer a serious concern.
Edit. There is no evidence that Cerberus is sabotaging quality at Remington.
