Nitto or Mickey Thompson

I did some looking around on FABO and this question has been touched on before but most of those threads are pretty old. The size intend to get is the 275/50R-15 and intend to race only but have to drive to the track.

So my question is what do you prefer? What has your experiences been with either?
Mickey Thompson 3451 Mickey Thompson ET Street S/S Tires | Summit Racing
Nitto Tires 108-610 Nitto NT 555 RII Tires | Summit Racing

The Nittos are a lot cheaper.

And, what do you like to run on the front, tire size?

Thanks.
