Most stable OS for FCP Studio 3?

Hi all,

Before i upgrade my rig i thought it best to check in and ask:

What is the most stable/best OS for FCP Studio 3?

i tried to do my due diligence but i could not find the answer on the Apple site...and the only other resource I trust is this amazing forum.

Am hopefully buying a Mac Pro tower today on ebay and have to specify which fresh OS will be installed...Lion, Snow Leopard, or Leopard.

Thank you so much and apologies for such a rudimentary question.

Best,
John

I'd advise Snow Leopard. Lion hasn't been out long enough to have all of the kinks worked out yet.

My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
More tools...
