Any known advantages to running the Durablend oils that say they are 1/2 dino and 1/2 synthetic ?

Summer temps usually 75-85 and winter usually 10-25 degrees. Sled usually only gets pulled 175 miles one way.

I have a 03 Silverado 5.3 with 10,000 miles. I am thinking of switching to synthetic but can't decide between Valvoline which is the only dino I've ever used, Mobil 1 or Penzoil. I know alot of people swear by Mobil 1 but is one any better than the other ? I mostly use truck for driving to work...
