I had a peterson's 4wd mag a while back & they got a bunch of donor JK's & tested different lift kits in all types of terrain & situations. They were all short arm kits. The tests were divided up in stages ( best on rocks, pavement, baja etc.) & each kit had a write up & grade for that portion of the tests, including strengths & weaknesses &/or if anything broke. Anyway long story short, the overall winner was a kit that retailed for over $2k, & the runner up was a 3" Black Diamond kit. It placed first in a couple categories, & the magazine basically stated that would be their choice for an all around best performance plus affordability. Other kits were a 3" Teraflex, Full Traction, Fabtec, Superlift & a couple more I can't remember. Quadratec sells the Black Diamond kit w/shocks for around $800 i believe.
