If a coin openly supports asics then everyone will get them, and the gains will be equal or even less compared to when everyone mines with gpu. But you will have more useless paperweight. Horrayy
Most of the neoscrypt based coins with masternodes are going to be pretty good. Or just mine some vivo or bulwark and you'll be good. Both looks really good and relatively safe. Goacoin is pretty high-risk atm so I wouldn't recommend it unless you're holding for months .
