there was much talk of monero's hard fork to get rid of asics being a risky move. however by this point it looks like it was a success and the forks that carried on with asics have now faded away.
some think asics make more sense from a security point of view, others think maintaining decentralization was the most important thing. which end of the spectrum are you on?
In this post on second graph is seen how hash rate of ZCash in April stopped growing and even declined. That means that GPU miners left ZCash for Monero. I guess ASIC miners were keep adding to ZCash.
