Personally I would go with the Yoko's, but I have them already.
1st Reason, Grip in the dry is just phenominal, probably has a lot to do with the solid block of rubber on the outer edge.
2nd Reason, Grip in the wet may not be the best in the world, but they are easy to predict in the wet, you know when theyre letting go way before they do. I love playing with mine in the wet. Must stress you may find other people cornering quicker, my older Falken FK-451's would of been quicker in the wet, but when they let go, they did suddenly.
3rd Reason they're asymetric as opposed to directional, so you can rotate your tyres easier than the toyos.
4th They look mint
Where the toyos look like every other tyre.
