Whether you like ASICs or not is kind of a null point considering they are being produced regardless.  I understand the argument that people will just buy more and the same amount of electricity will be used regardless.  This argument ignores all of the drawbacks to asics though and only considers the benefits of high hashrate with lower power.  Keep in mind:

1.  ASICs cost significantly more than a GPU
2.  They can only mine one algorithm

1. Depends on the ASIC and the GPU - there are at least 2 current Bitmain ASIC that cost less than a GTX 1070 much less the 1070ti 1080 1080ti or Vega.
  Even the current S9 models are in the SAME price range as a 1080 ti or higher-end Vega.

2. Not always the case - the Bailkal units in particular can ALL mine multiple algorithms, and the Gridseed / SFards chips were dual-algorithm.

In most cases though, an ASIC will completely blow away any GPU on what it CAN work on - it is more limited, but it is more capable by far WITHIN those limits (the Bitmain Ethereum ASIC is the ONLY exception, but even that thing is quite a bit cheaper for the same hashrate and very similar efficiency vs a 6-card GPU rig that achieves about the same hashrate) - which is why folks will continue to invest in ASIC miners despite their limitations.
