It is better in terms of the wireless charging capability and other extra features.

Despite being fairly similar looking they are 3 generations apart. There have been many technological advancements. Mainly speed and processing power. However, some good hardware additions are the improved camera and wireless charging capabilities.

Of course the 8 is better than the 6.

Other than losing the earbud jack it seems better, the one my wife got seems to have longer battery life. I was pleased that they didn't seem to be selling any ridiculously low memory models of the iPhone 8

I would say you have no need up upgrade yet if you are using a 6. If money is a concern SE or 6s might be good options.
I almost got one but since the iPhone 6 had a scratch, T-Mobile would not take it as a trade-in give us the second one free with new number added. So I only have a scratched screened iPod Touch that used to be an iPhone 6
