I guess it depends of what you have to do with the software and what kind of editor you are…
You would need a pick-up truck to haul wood and dirt and a sport car to race the track; Same thing goes with editing softwares!
I’ve worked on Discreet’s (now autodesk) fire/smoke as an editing tester in the past, after that I edited on Final Cut Pro (offline/online) with DV, HD material and my new contract is on Avid. Honestly I do prefer FCP as of now because I really don’t have much experience on Avid and I am still in the process of learning how to do stuff in this software… And even if Smoke/Fire are considered to be high-end editing systems (and I truly believe they are!), I would’nt like to do offline editing with those… But I’d love to offline in Final Cut. As for media managemen, it seems that Avid does a great job…
Each software has it’s pro’s and con’s and I guess each one has to look at what is their needs before considering any of the softwares available…
