Graphically, you really can't compare then yet. The PS4's most graphically advanced title is an fps, and the Xbone's is third person, and both have hugely different art styles. Comparing them on a graphical level from just trailers is essentially impossible, since your own preferences are going to warp your perception.
I'm just looking forward to Naughty Dog's first PS4 game :P They have been leading the console graphics race for years now.
Edit: In regards to Forza 5 and Driveclub, they are even as far as i'm concerned. Both seem to beat each other in different areas, so again, it will come down to personal preferences for now.
