MirrorFly vs RocketChat [Enterprise Level & Self-Hosted]

Does anyone have experience using MirrorFly and Rocket.Chat in an enterprise-level, self-hosted environment?

We are evaluating both platforms for a large organizational community and internal team collaboration. Key requirements include scalability, security, customization, ease of administration, and integration with project management tools.

I would appreciate hearing about the pros and cons of each platform, especially regarding deployment, maintenance, user experience, support, and overall reliability.

Any insights or recommendations would be very helpful.
