Air suspension and handling

[TotalControl]

Have seen quite a few cars lately having this mod done. Is air suspension now any better than a good coilover setup in regards to handling?

I'm a little old school in thinking it wouldn't be a patch on handling compared to a good damper/spring setup. Have things moved on much here or am I right with my thoughts?

Looks cool though.

At least I've learnt something. Always though all air suspension was fundamentally the same.

So the more expensive the system, the better it is or is that not true either?
