I don't claim that I know the ultimate truth, but I worked for many years for one of those big business software companies. But from my experience, only the people who don't have to interact with such products in any form like it. (Who are often also making the decision to purchase it)
It happened only a few times that users of such products (analysts, admins, support, devs, ...) told me that they like this or that. And I still remember each one of those guys and girls. (Weren't that many)
I know what those companies charge for their software and maintenance. I've been involved in the development of those products for a couple of years. And my very personal opinion is: they're not worth their money. No matter what a customer tells the press how much easier their business is after purchasing product X from company Y.
As I said, it's my personal opinion on that matter.
