The biggest reason is aftermarket support of the engines. A Chevy or Ford engine has lots of aftermarket support, headers, chips, heads, intakes, etc. The mopar line doesn't have as strong of an aftermarket support, so the prices to modify mopar engines are higher than doing the same changes to Chevy's or Ford's engines.
As far as the weight of the engine goes, the heavier the engine, the harder it is to balance the weight on the Jeep - but it can be done. The Ford's and Chevy's engines are light enough that stock or even aftermarket suspension can handle the little bit of extra weight difference over the weight of the stock 2.5 or 4.0 engines.
