My experience was that I liked it more than AdManager but even while hosting OpenX myself , I noticed a lot of chatter going back to their servers. Also, I had to do constant battle to keep out malware ads. Even when I had limited it to just a few networks that I kinda trust, I had hack attempts to insert malware ads into my inventory.
Like I said, it's better for me than AdManager but I don't think it's a whole lot more private and I think Google does a better job of keeping the inventory from their networks cleaner.
Don't know how Microsoft will do with a GPL property but I like seeing competition against G.
