What parts of notion are you claiming are fast and responsive?
In my experience using the web app is very slow, and search is monstrously slow. We still use it but slowness is our chief complaint for the platform.
When loading it absolutely takes 4-6 seconds to complete rendering.
If you’re talking about intra-page actions like adding a complex ui element after load you’re right it is better then Jira in that regard.
I’ve been part of a team doing JIRA and Confluence configuration. We saw on,y the tiniest bit about the configuration process required to make it work, and we slammed that hood right back down and decided we were never going to look under there again. Well, not ourselves. But we did hire a JIRA and Confluence expert to come in and help us make it as optimized as we could get.
I’ve also been a customer of bad JIRA and Confluence configurations. And when they’re bad, they can be really bad. But, as a customer, you don’t have any control over those system configuration options.
It’s like saying that a hammer is bad. Well, which hammer did you use? There are dozens or hundreds of different types of hammers out there. How did you use this hammer? What did you use this hammer on? Where did you use this hammer? Were you trained in how to use it properly? Did you actually use it properly, or were you using it in a way that was not consistent with its design?
There is no one JIRA or Confluence.
I hang on in the hopes they will address the problem.

Notion is more for sharing a set of documents that are often used. And thus create some hierarchy of content without right management or structure. Works well if you are business owner or a team, or a small company. Or if you want to onboard noob users into documenting their work. And Notion is very good at that
Confluence works better to manage a lot of documents, give rights, structure content, organize. Confluence is not very good at it, but this is a difficult task and competitors don't do better
So depending on where you are at, you can pick the one which suits you best. They are others less popular tools than Confluence and Notion but still are in the two categories described above
