Pro Evo on the 3DS is pretty good and the 3DS effect is subtle but adds a lot to the gameplay. The depth of the pitch and you players is spot on - I am still amazed at the 3D effect on the 3DS tbh and just love watching back some of the replays - never done this before on any footie game!
Played this more than Ridge Racer and Pilotwings - so that says quite a lot I guess.
I got a chance to briefly try a 3DS today in a shop but couldn't really see it properly. The graphics looked a bit messed up to me and tried moving the depth slider but couldn't get it right. I was a bit pushed for time so didn't get long with it but I think it takes a bit of getting used to.
