Both have their pros and cons. At the moment, AMD certainly is a more appealing choice: cheaper, more power efficient and powerful. Intel is on a node that they have been on for the past several years and don't see to be advancing near AMD as of yet.
But it does come down to preference, while I would recommend AMD (right now), Intel is great too.

There is literally no reason to pick up Intel over Amd right now. Amd has smaller nm process, better power efficency and faster. Also the new 5000 series are faster on single core, which was intels only advantage until now. So that means amd is better for gaming aswell.
