Also depends on the resolution you'll be gaming at (720p, 1080p, 4K, etc.), if there is any price difference between the Intel/AMD motherboards, & what your total budget is.
If the boards are also pretty much identical in price (& I mean within $25-50 USD or equivalent), then go with the Intel because cost isn't a factor. If the margin is greater (especially if it's over $100 USD), then going AMD means you can get a more powerful GPU, possibly combine an SSD and HDD in your build, maybe add additional RAM, etc.
