Some questions I feel are missing:

- Which manufacturer sells the most profitable hardware (historically)?
- Which manufacturer sells hardware best designed for the home?
- Which manufacturer ships on time the most?

2nd two are ok first one is not. The reason for it is simple profit is determined by the person who has the equipment, how they purchased, when they purchased, how much it costs in power.

For that one I would still say SP, SP has been more profitable on equipment than any of the other companies (baring if you had one of the first few BFL products), Bitmain has sold equipment and before the units even shipped dropped the price by a decent amount, their reaction was literally a shrug like o well.

Second question is a bit better, still personal preference tho, I don't really mind any noise that is constant as long as it doesn't change frequently I could care less at noise level, exposed PCB's are not something I'd like lying around my house.

Third question, very favorable towards Bitmain, if I'm not mistaken they have missed a shipping deadline once or twice before, but then again they ship from farms.

Putting a why did you select this answer is a good way to actually judge the meanings of the answers.

Something like,
1) Which manufacturer sells hardware best designed for the home?
1a) Why did you make that selection

2) Which manufacturer sells hardware best designed for a data center?
2a) Why....

Using only multiple choice causes a problem where every question can be "sided" towards one person / company, if you've ever participated in research surveys you should know that most of the questions are scale based or put in your own text / explanation. (I've both made / calculated the results and participated in these)
