Reviews of Slack

Karen
Realtime notifications
Comments: I use slack with the finance teams of the clients I work with. We use slack to send questions and get rapid responses.
Pros:
I work with clients all around the world, Slack is the best communication tool I have used. I am able to finish projects faster and more accurately with clients that use Slack than when using Email.
Cons:
Switching from businesses is some what complicated in the mobile app.
Alternatives Considered: Microsoft Teams
Reasons for Choosing Slack: I changed jobs
Switched From: Microsoft Teams
Reasons for Switching to Slack: Not a lot of clients wanted to use teams and some feel like teams is spying on them.
Goran
The only way to communicate within a team
Comments: I use it for all manners of communication with my team - from quick huddles when we get stuck and need a rubber ducky moment, to bigger team meetings. We have groups for smaller teams to collaborate in, we have fun channels to blow off steam, and we even use it for the food train organization.
Pros:
It is easy to use and feels natural. For us coming from Discord or IRC, it is very intuitive to understand how to use it without any learning curve whatsoever. Slack helps me connect with coworkers, share project updates, send cat photos to my team, send random funny quotes, gifs, reactions, all of it still in a very professional application that handles all of my communication needs.
Cons:
Slack sometimes becomes too much, but it is easy to mute it to focus on work so this is easily solveable.
Alternatives Considered: Microsoft Teams
Reasons for Choosing Slack: Discord is a gaming software and with our company becoming more serious, we wanted a more serious solution.
Switched From: Discord
Reasons for Switching to Slack: As we later learned and originally suspected, Microsof Teams is much harder to use and is much less intuitive and fun.
Matija
Comunication tool for biger projects
Comments: We use it for specific international project and overall we receive what we wanted: faster connection than email and quick tool for sharing the documents.
Pros:
Segmentation of the channels for specific parts of the project and easy drag and drop tool for attachments.
Cons:
Need for a daily login from all members of the project and understanding how channels are working.
Alternatives Considered: Basecamp, monday.com and Asana
Reasons for Switching to Slack: More people new about Slack then about other tools.
Abhinav
Best Tool for Team Management and Coordination
Comments: Overall I love to use it and provided it has the support of integration with almost all of my tools it works as notification engine too which is one of the awesome parts of this tool.
Pros:
Slack is my daily used software for all the team meetings and sharing work details. I like it has all the features built-in that are necessary for an enterprise team management from sharing of files and chatting to video or audio conferencing.
Cons:
The support team is slow in case of any problem tho hardly we face any issue with this software it's highly reliable and one of the best things I use on daily basis.
Alternatives Considered: Google Chat, Trello, Zoom Meetings and Microsoft Teams
Reasons for Choosing Slack: I love the overall look and feel of slack and its support for integrations.
Switched From: Google Chat and Microsoft Teams

Slack is the ultimate team-discourse application
Comments: Slack has drastically increased our workplace productivity, especially by promoting communication between those that work in the office, and those that work at home.
Pros:
Slack manages to maintain a comfortable work-home boundary with the introduction of different channels. The ability to create "private" channels within a workspace also helps to build community. File sharing is convenient and easy to understand, and the notification settings are remarkable.
Cons:
Often if a notification is received on one device (i.e. laptop) it will not always push to another (i.e. phone)
Alternatives Considered: Microsoft Teams
Reasons for Choosing Slack: More secure.
Switched From: Discord
Reasons for Switching to Slack: Convenience and use by the rest of the university.
