Asic is a piece of iron. It is expensive, on the secondary market is not in demand. As a rule, it's very dinny and consumes electricity. The profit falls very quickly, only those customers who will receive the first are the winners + problems with the guarantee.
The GPU has fewer problems and can be sold in the secondary market
The GPU is toast after a year of mining and NOBODY WILL WANT IT.
Gonna be a flood of used miner cards on ebay - people will soon learn they aren't worth shit for reliability! Any hardcore PC gamer knows gfx cards have a usage life depending on how hard you push em much like a car! cars with high miles = worth jack shit.
With gfx tech increasing rapidly right now fueld by crypto, you can bet that 1080/vega or whatever will be worth $60 in a year (+ shipping and ebay/paypal fees) so the resale price point doesn;t mean much.
I'd much rather have twice the production per unit of time/energy/$$ because lets be honet right now its about who can most the most the fastest speculating on a future price increase and known diffcullty scaling.
TLDR:
The asic miners blow gfx cards out of the water no doubt about it.
And this news of secret asic miners taking HUGE chunks of monero, zcash, etc, WTF??
crypto for the hobby gfx card miner is dead most just don't realize it (which fuels the at home gfx card hobby miner market).
