I've gone to them each year for the past decade, or so, and quite enjoyed them. They can vary a bit from year to year depending on the speakers.
There are videos of several of the past speakers online. For instance https://www.ivey.uwo.ca/bengrahaminvesting/resources/video-library/
The online format is new for them. So, it'll be interesting to see how they handle it. (The networking and side meetings were really good in the past but, alas, probably won't happen this year.)
If cost isn't an issue, I'd go for sure. But it's mostly an industry thing for those who can write off / expense the cost. It'd be a harder decision for retail investors of modest means. The later group might want to wait till next year for the full experience.
