More hp or an extra gear?

I read where the 2016 Ford F53 chassis changed to a 6 speed transmission, but for emissions regs. dropped the horsepower rating down to 320 from 362 on the 2015 chassis. So if you were buying a gas class A today would you rather have the 5 speed with more hp, or the new 6 speed with 320 hp?(And you can't answer that you want 362 hp with 6 speeds?)
