Microsoft Teams is ideal for organizations where employees regularly collaborate by sharing files, working on the same documents, updating the progress, etc. This is because different file formats are supported for online editing and collaboration with the help of Microsoft Teams. Additionally, for every file which is shared among the team members, emails are not sent again and again which helps in easily managing and organizing files. It is less appropriate where the team members have to instantly reply to an urgent task as sometimes the notifications are not sent properly which may lead to a delay in the work.

Slack is really effective for smaller teams to use as an internal communication platform. I think that it's still suitable even for companies of up to 500-1000 employees, but for larger teams it's less appropriate (or would require more aggressive organization, e.g. keeping channels protected and on an invite-only basis). It's really helpful for small team-to-small team communication too (like in our case where we create external channels to support POCs/business partnerships). It's not great for direct collaboration (e.g. it's hard to iterate on a project spec or a document together, directly in Slack) but it's well suited for conversational coordination, like planning meetings or asking informational questions.

Pros
  • Video calls are great with Microsoft Teams. They've made big improvements over the last year and I rarely have issue with getting on. It's nice when things just work.
  • The most used functionality is, of course, the chat feature. It does what it's supposed to do and you can create chat groups from whoever you'd like. We use it a lot when there is a special project and a team from various groups get together for a short period of time to get things done.
  • An overlooked function is the ability to search anything within Microsoft Teams. Any photo, document, or chat can be searched and found pretty easily. I can't tell you how many times this has saved me from having to rewrite something or start over.

  • Huddles Run smoothly without any interferences.
  • Smooth individual calls quick and easy without any interruptions.
  • seamless notifications across multiple devices
  • The ability to easily tag a team member to urgently attend to a specific escalation.
  • Slack being user friendly and able to integrate easily with other platforms and apps.
  • How to easily open up different channels for different escalations and needs.
  • a safe direct messaging option.

Cons
  • I sometimes have a hard time viewing both the meeting screen and chat window at the same time.
  • There have been times when someone in a meeting will totally lose their connection.
  • At times the sound quality is not what it should be which makes it hard to hear each other.
Read full review
  • Undoubtedly Slack’s search function is powerful but sometimes it is difficult to find specific messages or files in very active channels with high message volumes. This needs an improvement.
  • I have experienced notification issues on my phone. I am not receiving notifications and have missed important updates as a result. I tried uninstalling and reinstalling the app, but the problem still persists.
  • The Business Plus plan does not include support for data loss prevention or offline backup providers.

Microsoft Teams is included with our Office 365 subscription and we have no intention of migrating off of Office 365 and Microsoft products.

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

I think Microsoft Team is overall good application for communication, track Project work inter the teams and also intra teams.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.
