I can vouch for it being worse than JIRA, which I was absolutely not prepared for when I moved to a company that uses Notion for its ticketing system.

Yes, worse but it depends on what type of page you're working in. If it's of medium complexity and up, it's worse (a few media elements, maybe a database, etc.)

If it's just text, it's faster than JIRA or Teams.

I have the same problem, I understand the enjoyment of sales / marketing team when it comes to using Notion, but for engineering team, it's just horrible, so slow.

Not in my experience. Notion is faster than Jira. But we don't have super massive wikis, hundreds of pages at most.
