Very interesting video! I have to say I have not really considered changing my cursor much since the heyday of ~2006 Myspace cursor type things. I've sent this tab to my home desktop to give it a try when I get home.

I often find myself gravitating towards sleeker, flashier looking cursors (like a chevron) but sooner or later get annoyed or confused and switch back to the old angled-triangle-wtih-tail.

I'm interested if anyone else has thought more about mouse cursors in recent years and what your findings were!
