I think you need to make it clear what standard you use to list them as "the best". <snip>
The' Best' all depends on the buyer - not some random person's thoughts... Most hardware guides here are pretty clear on that: 1st pick
your criteria and choose from either speed, efficiency or, service life and go from there. There are no miners that are the top in all 3 areas.
Personally I use service life as my #1 and that means any of Canaaan's Avalon miners.
In normal use, according to your experience, which ones get less issues? Antimners or Canaan?
