Would the iPhone 8 be a good upgrade compared to the 6s?

I have had an iPhone 6s for 2 years now and I was just wondering if the iPhone 8 would be a good upgrade considering it still has the same design and size.

It wouldn't be. The biggest difference is the price. Not joking.

Well its more than just the external factors that matter.

The internals would be much improved from a 6s.
