We've driven both. In my opinion, they are both scenic. Hwy 16 is more rolling hills, so much our sofa shifted while driving this route! Hwy 14 is more mountainous and high elevation forest. We towed up it with a smaller trailer and were fine, but passed a Class A that ran off the side, so take it easy and slow.
