I would describe it as a very stable Falcon 4 base install with all the superpak edits. I have flown 40+ missions without a CTD. Multiplayer code has been rewritten and I have joined several online campaigns that run 24/7 without a hickup. The other improvements are OCA strike menu for your flight. Now you can have multiple targets selected and hit with one pass over an enemy airbase. You get the balkans theater which has been fun. Ayes cockpits, improved ATC, and working awacs which has gotten the field general types happy. It has been a lot of fun, and sets a new base to build from. Not all shinny as what you can piece together with the patch dance, but a new controlled beginning that will surpass anything that the old code could do.
