- Users say that Slack's implementation process is notably quick and intuitive, with many highlighting the ease of setup as a major advantage. In contrast, Output Messenger, while user-friendly, lacks the same level of praise for its onboarding experience.
- Reviewers mention that Slack's extensive integrations are a game-changer, allowing teams to optimize their communication and reduce the need for meetings. This flexibility is a standout feature that many users find invaluable, whereas Output Messenger, while simple to use, does not offer the same breadth of integrations.
- According to verified reviews, Slack's quality of support is highly rated, with users noting responsive assistance when issues arise. On the other hand, Output Messenger's support is perceived as less robust, which may be a concern for businesses that require reliable help.

However, Output Messenger's search capabilities are noted as a strong point, indicating that it can effectively handle messaging and file sharing, even if it lacks some of the advanced features found in Slack.
