HashFast's chips are about 3 times more powerful when compared on a GH per sq.mm basis.
HashFast is shipping with top-shelf quality Sea Sonic PSUs, so our customers won't have to put up with exploding/self-immolating units like KNC's did.
In addition, HashFast lined up an exclusive with CIARA, which means HashFast machines will be assembled and shipped with utmost expediency (no random guys helping load some random van), in professional/durable packaging.
That means double-walled boxes, so HashFast customers' hardware won't arrive broken like so much of KNC's did.
Finally, (again unlike KNC) HashFast has been working closely with ckolivas for a long time to ensure cgminer works flawlessly with our innovative new GN Protocol, Global Work Queue, etc.
After 70 days mining every one of my batch #1 Jupiters have mined aprox. 50 BTC each - let's see how many BTC will your batch #1 units mine in their first 70 days of life.
That (BTC MINED/DAY) is the only thing that matters right now. Power costs are so ridiculously marginal at this stage that bragging about efficiency is just ludicrous.
I'm glad you are satisfied with your past ROI, but don't see the use or validity of comparing it to future returns.
In fact, the hash power which earned you that nice ROI in the past is exactly why future ROIs will be lower!
You could go all the way back to Gen One Avalons if you really want to highlight the past vs future contrast.
HashFast cannot control difficulty, nor make investment/speculation/gambling decisions for its customers.
We can however learn from KNC and others' mistakes, and control our choices of flawless cgminer support, high-quality Sea Sonic PSUs, world-class CIARA assembly, and professional logistics which includes packaging adequate to prevent damage in shipping.
Judging by the uproar in the KnC thread(s) over these issues, they do matter to many customers.
Best,
