I prefer Antminer s7 on Avalon 6.
The new Antminer S7 Plus is much more efficient.
There's not a S7+ version, am i misunderstanding?
And now the latest batches of S7's have the same efficiency as the Avalon6, so not the only reason to stick with S7 is the GH/$, since the Avalon6 has a much better build quality.
No misunderstanding there is not a S7+. It would not suprise me if they do have one day... but no sign of it yet. Right now they have batch 9 that is cheaper so they won't do any change before that goes to sale.
If they were going to change product it would be after then. But I'm not sure they might milk current design a few more batches. They have a design ow with less chips and high freq. Which should mean more profit for them.
