Canvas has substantially improved its Respondus integration for New Quizzes last year. Settings now carry over on course copy which used to be a big pain point, setting every assignment up from scratch for every course.
The big advantage is of course that Respondus is free to the student. I think there are issues with pay-to-test formats.
I would advise against thinking of video recording tools such as Respondus as proctoring. Because students aren't watched live, there are tons of behaviors that would trigger an intervention by a proctor which you can't do anything about when you are watching a video later because you can't prove the misconduct. Also, one should not underestimate the instructor workload of having to manually check the videos.
These tools are necessary if you want to have an idea of who is taking a test. Without them, it's probably one of the cheating organizations that's completing your courses. But I would think of them as identity verification, not proctoring.
What do you mean by "learner logs"? I am unfamiliar with that term.
