I personally would go with the adjustables as they allow you fine tune your caster for better handling. Some people go with the fixed length and seem perfectly happy with performance. If you are ever going to go higher on your lift however, then your fixed length are not going to help you whereas adj. would. Just a thought....

Fixed are cheaper, but adjustables are worth the extra price. And if you do rear ca's, consider uppers instead of lowers.
(upper or lower will work for either end, but front lowers and rear uppers are generally considered to be the better choices if you only do one set)

In the rear, its the opposite. The rear axle needs to be rolled back by lengthening the upper or shortening the lower to line the pinon angle up with the drive shaft. Shortening the lower pulls the tire into the rear pinch seam slightly. Lengthening the upper centers the axle slightly better.

Pro fixed: Cheap (assuming we're talking stock arms), light weight, perfect alignment with Geometry Correction Brackets.
Con fixed: Can't adjust if needed, camber will be wrong without correction brackets, not as much flex, not as strong, some ground clearance is lost if brackets are used.
Pro adjustable: They are, well, adjustable. More flex, stronger, better ground clearance.
Con adjustable: Steering works real nice with dropped CA mounts when using the bracket, more weight, more cost, need a way to measure castor.
Edit: Talking just fronts here. Adjustables are needed in the back for sure.
