Why do you have to jump ship? Just get the 10 and see how they compare side by side? The Canaan miners seems "better" in terms of design and performance.
"Jump ship" is a relative statement... kind of like someone who has always bought Fords and finally buys a Chevy. Obviously I'm not going to throw away my existing S9s. Its just that I've been buying from Bitmain since Antminer U1 days.
