I've seen comments on IINA that it is a better video player than VLC and that it runs all popular video files. Clearly it is not better in several ways. It is a fair argument that many have made that IINA has a better user interface. But does it live up to the frequent hype that it is has better "performance" than VLC? Clearly it does not perform better with regards to playing DVDs, and for all I know the same may apply to many other video file formats.
I was mislead by all the hype all over the web that I should switch to IINA. I tried it and thank GOD I discovered early on, before I invested a lot of time learning to use most of its features, that all those people lauding it were really quite ignorant of its deficiencies.
