I can't nor can anybody else tell you what is better. Its all you, and mainly its all feel. What people are referring to are the frame notch to lay frame and be even on both sides. Its typically reinforced with steel and does not weaken your structural integrity. I'll give you one of the reasons I decide to stay static, I want to ride low. But, typically on an air setup to be low you have to be at low psi and the ride is "rough" from what I read. Plus, I see that I ride lower on coils then a lot of people on air near me, except when they are trying to do a photoshoot. Also, on air you should really know your system all around to know how to identify a quick leak and where, how to replace a bag just in case it blows so you are not stranded, etc. I don't doubt people will try to refute what I said, but hopefully everybody's individual opinion can help you decide.
