I am moving to Phoenix too, dual mining becomes unprofitable, miner is unstable, devfee is huge for Claymore.
I really hope claymore will lower its devfee overall because phoenix miner is much better overall right now and its devfee is 35% lower.
My take on the two miners
I was a Phoenix fan. Ran it for few a few months.
It is good.
Solid miner.
Hash rate was higher.
Dev fee was lower.
However since I started testing Claymore again starting with v 11.3 and now 11.4
It is good.
Solid Miner.
Hash rate the same or even higher for me than Phoenix now.
Feature rich miner, far more detailed features than Phoenix at present.
Just the setting for temp and clocking alone is far better.
Much lower stale share rate by a large factor than Phoenix.
Claymore fixing the stale share rate alone paid for my 1% dev fee they charge.
Gotta give the nod to Claymore at this time.
These are my experiences and my opinions, you're testing may be different than mine.
