Advantage of GPU over the Baikal ASIC is that if diff goes nuts in Dash (which is likely) or price falls (which is also likely) a GPU can mine about 100 other coins that Baikal cannot.
well a baikal can mine 6 algo not only one, so you have some other option in case x11 tank, it's also true that if dash tank other coins can not sustain its hash
Agreed, there are some other options. But none of them as profitable, and while I am a fan of Baikal/Dash I would still argue that GPU most likely have better resale value and wider application area.
Not saying Baikal is a bad value, just pointing out limitations.
