I have worked with a number of Learning Management Systems. Some of which no longer exist and/or have been bought and swallowed up by the more major players in the industry. I have seen the industry change - at least most with helping the student succeed in mind.
One thing that I really appreciate about Canvas is that, 1. not only did they develop their own mobile app, but, 2. they offer it as part of the purchase package and it's already configured!
If you have never had to beat your head against the wall dealing with "some of the other major players" then consider yourself lucky.
I have twenty-one years of experience in Higher Education in Faculty Development and LMS Admin roles as Title III Director, Director of Distance Learning, and Director-Center for Excellence. I have worked at or consulted for multi-campus community college systems, private universities, global insurance and healthcare companies, and the US Air Force.
