I have had both good and bad experiences with each. It really gets down to the type of work you do, whether you prefer Mac or PC and whether you have a good source for support. With Avid you get a sole-source supplier and a good (in most areas) dealer network. This doesn’t exist with Apple when you combine Apple products with 3rd party hardware, unless you have a dealer to provide all the support. That doesn’t mean you’ll have a bad experience, simply that support falls more in your own hands when it is needed.
Adrenaline is a good product after some early shakiness, but the prevailing opinion is that the PC versions are more stable. There are, however, happy Adrenaline Mac customers. The Avid Media Composer Adrenalines are faster in most things than the Meridien predecessors, but not as rock solid. You can chalk that up to the Firewire connectivity of the Adrenaline chassis, versus an installed boardset. I know you said cost isn’t a factor, but you will have to evaluate long term ownership costs, such as Avid Assurance, upgrades, etc.
As far as FCP5, I don’t believe actual Media Management has changed. There’s too much rewriting involved, so for offline/online workflow, Avid is hard to beat. On the other hand, Apple claims to have rewritten things like image scaling, which should make the quality of DVE moves much better in FCP5 than previous versions.
