I haven't used them for real but (briefly) evaluated with the intention to maybe replace Jira, about a year ago.
Space wasn't there yet. IIRC the main issue was lack of a way to set custom fields via API, or some weird restriction around that. My general impression was that it was promising but too immature at that time.
For any Jira competitors reading this - start with providing 2-way sync between your product and Jira instance. It would make moving away from Jira soooo much easier!
The current state is that even importing Jira data is below what I'd expect - e.g. Linear (last time I checked) didn't import comments at all and all issue IDs were changed to new ones. Really, if there's FOO-123 in Jira it's table stakes for it to be also called FOO-123 in the new tool.
I wrote a tool to migrate an issue tracker to Jira which imported everything as expected and updated links in issue descriptions/comments to keep their integrity. It took few days for a one-time migration so I'd expect someone who builds a business in this area to just have that as a baseline. It's sad how bad the "import from Jira" journeys are.
