Qualtrics is pretty popular among their initial target audience mentioned in the article: academics. Among academic survey shops this product is the definite go-to.
I imagine, based on my own experience, the average tech worker thinks of surveys as small sets of questions used to easily and quickly collect a few data points. SurveyMonkey is fine for that. But for the types of real surveys that provide the data for serious research, Qualtrics is what you need. I've used it for government surveys, sociological, health/medical, etc., web and in-person, with lots of flow control, randomization, and all the other features needed to produce robust and accurate data.
