Theres a million opinions, not than anyone of them is particularly right.
Theres absolutely nothing wrong with a 3 link with a wishbone, built and installed properly they are one of the best riding setups, simple, clean, they work.. the reason why 75% of fab shops put it on a lot of builds.
bolt on kits are great if you dont have much fabrication skill or experience.
hydrolic line is great, but if ran properly plastic airline is plenty durable.. i know a lot of people that run it on dailys and never have issues.
front like brett said, no need to spend big bucks if youre on small wheels.
2 links are not my favorite , but they do work depending on how much adjustability you want driving.. some of the big shops run them on their dailys and they know more about air suspension then 90% of people on here so they arent that terrible lol.
all that being said its only my opinion, dont mean everyone should follow it!
