^I'd agree with that. Each brand, and even then, to break it down, each individual lift, has its ups and downs. Here's a general rundown:
Rock Krawler- off-road focused- killer flex, and not bad on-road (what I run in mine)
Teraflex- good on-road and not bad off (Their shocks are rather soft for my liking)
Old Man Emu- probably the best mix of on and off-road comfort, but zero frills, so you'll have to add on from other companies if you want more than bare basics
Rough Country- garbage, pure and simple
Skyjacker- alright on-road, alright off. I'd look elsewhere
Black Diamond/Superlift- good shocks- good on-road, decent off-road
Then you can break it down further from there. Due to the WIDE variety, I'll let you pick and choose. For 35's, between 2.5 and 4" is what you need. 2.5" will be fine for a DD that doesn't need much extra flex off-road. 3.5-4" is what you need for hardcore rocks and 35's.
Also, you'll need to consider gearing- 4.88 or 5.13 is what you need for 35's with the automatic, 5.13 being the better pick.
Hope this helps some- Mark W.
