Is Github Issues better than Trello?

Our team started out with Bitbucket+Trello 5 years ago (I guess because Estonia has a long history with Atlassian products). Since then we have moved our codebase to Github but have kept Trello. We are quite happy with it but I was wondering if we are missing out some nice developers experience because of this setup…

For some context: we develop multiple products, each product usually has multiple code repositories and even more Trello boards. Trello is being used by developers and customer support. We have also built a Github action https://github.com/rematocorp/trello-integration-action that integrates these two worlds as much as possible.

Do you think we should consider moving our setup to Github Issues?
