I can't see us considering a migration to another tool for at least a few years.
Edit - doing to considering
Ultimately we went back to JIRA because clubhouse thought differently about agile workflow than we do. At the time, clubhouse didn't support sprints other than by adding labels - but the reports didn't reflect the sprint temporal boundaries. We found it really hard to create things like a view on sprint velocity. We also didn't agree with their view on what a team is but I forget the specifics.
It wasn't that JIRA is perfect, but it was either less wrong or more right depending on your perspective.
I am a fan of the newer Portfolio/Plan functionality in JIRA which I think replicates some of the features I liked about clubhouse, in forcing a large to small PBR, but I don't use the date planning features.
