I have run both. Can't get traction with Nitto DR below 55*.
I switched to the MT ET w/ tubes. At 18psi they are fine, but depending on your set up you may need to go with 14psi which requires a tall bottle of courage at the top end on occasion based on track conditions.
My opinion about the Nitto DR is they are a crappy street tire and a crappy track tire. One big compromise and I will never buy them again. They are only good for a burn out contest.
Many have spoken highly about the MT DR.
You can do a search on threads I started for a detail.
See Pic for how bad Nitto DR are in cool weather;
