Well..... Body lift is much cheaper, and gives you room for bigger
tires, and saves all the added stress on the driveline and related
parts, but you have the steering and T-case/shifter levers to fix
so they work right, and can be a lot of work.
Suspension gives you room for tires also, but is expensive, but
it also gives added articulation for awsome offroad traction action.
It stresses the driveline, front axle, front CV joints, slipyoke hangs
out a little farther than I like and wears the bearing over time.
So what to do, I did the suspension and decided to do the body
for some big tires, I built both lifts as I never have an extra
grand just clogging up my bank account.
I think suspension is a little easier to do, as it is all just bolt
on parts, can be done in 8 hours if you know exactly how it
all goes on, and have all the tools right there.
I think the Cal-Mini drop axle is a weak point, I have 3" suspension
and kept the front axle in the stock location, CVs are a little more
stressed and at the end of their cup travel, but have worked fine
for years, I just had an outer CV clicking, sounds like a birfield
going out, which is from my understanding the same design
as a CV joint (ball bearings in a cup) so I installed a low mile
CV shaft from a towed low mile Track\Kick I found at the
pic-a-part yard.
I'm going to work on slip type front wheel driveshafts
refitted with U-joints to eliminate the CVs and get some
more travel, the stockers are at their limit with 3" suspension
lift.
So with the pros and cons, It's really up to you.
Good Luck
