My company did. We moved to ClickUp. It is much better
We also migrated to ClickUp (though not from Jira) but while it's better than what we used before, it still feels... I don't know, sluggish. Loaders everywhere, lists are jumping when you scroll. Sometimes I click on a task, the detail modal opens up and there is a noticable delay while the data loads. Typing a / in the description which opens up the command panel or integration panal or whatever it called, freezes everything for like 100ms or more.
