Squarespace courses vs a third party like ticket tailor for live events

I want to sell seats/tickets for live online classes and in-person classes. They are typically two days long. I have stripe set up. What is the best way to sell tickets? A third party product such as ticket tailor? And if so, which one is best? Or is it better to use the courses product on Squarespace and their checkout flow? It's really not clear and it looks like few people do this. Which I'm surprised about. Currently I use eventbrite but my admin complains about it and it is expensive for what you get.
