As I said on http://turbo.gamedev.net forums, for more information on PowerDraw, look at http://turbo.gamedev.net/powerdraw.asp. Due to my lack of knowledge of Project Omega, I wouldn't compare the two components and I think it's not ethical for me to do it anyway - so I think you'd take a look at examples, site and other info and decide yourself - besides, it all depends on project's needs.
