I liked my 47 Chevy truck on bags. Rode well, infinite adjustment and for some reason people really liked to see it settling down when dumping air at a show.
My next truck project is a 1948 Suburban on airbags so apparently I like them well enough.
Which is better really depends on what you want you truck to do, and on who you ask. I know people who would debate either side of the subject.
Properly done they are reliable. Lot's of semi trucks on the road with them.
