Very little mpg difference and more reliable and more power.
My 2 cents
Did they FINALLY fix the timing chain failures that start at about 100K miles.
I will not buy the 3.6 for that reason. All the chain, sprockets, guides tensioners etc it is well over $1000, some run $2500.

The V6 has been completely redesigned for 2017. It uses a different timing chain design. Same as the new Camaro/Cadillac V6. http://gmauthority.com/blog/gm/gm-engines/lgx/
Camshaft drive: all-new, with a simpler design featuring two chains and six sprockets vs. the previous three chains and nine sprockets, with lower chain loads, which enhances durability. The lower tension of the chain drive, along with cushioned ring sprockets, also reduces noise and vibration.
Also the new truck uses an eight speed automatic transmission.
My 2017 V6 auto gets an average of 25 mpg in suburban/rural/city driving. I love the truck. I went from a full size GMC Sierra and the smaller truck is a joy to drive.
