I have seen many flaky ASUS and MSI boards, and Zotac isn't exactly known for their support. Had Gigabyte products for years with no issues, switched to EVGA recently so far so good, and they supposedly have excellent support service
You have a point since it's got really good price to performance, but this is a poll for gtx 1070s only, so I would recommend creating one here if you prefer amd graphics: https://www.massdrop.com/poll/create
My personal favorite is the one by ASUS, but they are all great, so I recommend ASUS obviously, but chose who you want and try to recommend this to others so we can try to get a good drop going so we can fight the mining prices.
