OK NItto Terra Grapplers or Toyo Open country M/T

Ok guys,  I thought I was set on getting Nitto grapplers A/T's 325/60/18's, but when I went to my local off road shop the salesman said that the Toyo Open Country Mud Terrains 33/12.50/18 are very quiet on the highway and his other customers have been getting 50K plus miles on them.    What do you think?  Is he just trying to get me to buy a more expensive tire.
 
I would much rather go with the more aggressive look and performance of a M/T especially if I can get 50K and have little road noise.  Are the Nitto's getting similiar mileage? 
 
All thoughts would be appreciated.  Also, I will either go with the Helo Maxx's or Boss 304 wheels.  Any issues with fit?
 
Thanks in advance.

Just noticed, it is a 2007 H3. 

I'd go with the Nitto Grapplers.  It looks meaner IMO.
