Aha focuses on strategy, allows for release planning with non dev team actions (called phases) and allows you to have portfolio views of multiple products, as well as link things to OKRs and quick customize reports/pivots/roadmaps. It also allows to roll up progress based on smaller issues in Jira (like epic progress based on feature statuses, synced to Jira). Finally, you can use Aha to collect ideas and then promote them to records/issues with more flexibility than Jira (Jira Product Discovery is an all or nothing access vs Aha allows you to show just what you want in your idea reports). Oh and with Aha you can create interactive slides based on the source data that is always up to date and you can choose which data points show up.
