SalesForce ticks enough checkboxes. Competing products may tick the boxes too, but without great marketing that won’t matter, the company that can sell their product will win.

My point was that SalesForce has fairly poor user experience and performance, but does offer the features. It has the additional advantage (for SalesForce) or quick lock-in once the customer commits to it. SalesForce has improved the user experience over time because they have the customer base and revenue to allow that.
