Microsoft Teams

Pros

The integration with Sharepoint and Office 365 tools is really awesome, works very well, and also you can create and built-in Apps from Power Plataform inside your Teams's Group, and do not forget that you have all the Office 365 Apps to integrate within your groups (the number of the Apps will vary depending on your signature).

Cons

I believe that the price is not so good to medium/small companies, that probably will use a less professional tool, or a freeware with limitations.

Pros

My organization ( if they are well trained) are always available for a call.
Mobile or Desktop, Cloud or web. Not need to be bothered by the downloads and install, Teams allows for meeting to take place in any location, with Web, Mobile or Desktop.
I love the fact you can transfer and I once used the CC -close caption - but seem to have been disabled.
Teams allow you to share with external guest ( persons) for meeting, but it is not straight forwards as one expects

Cons

Great tool, good clarity but sharing a meeting with an external client, It is sometimes troubling and not clear as other platform.
It is also a bit difficult for regular user to ensure that meeting are secured when the link is shared.
Anyone with a link for a meeting seem to be able to join the meeting. The only barrier is a good host who sits and allows users to enter, as the notification will pop up.
Most small meeting don't have dedicated host and small offices are left unaware of this leaving teams as an open meeting - for anyone who has the link.
Wish they just had a simple interface for external meeting, I know about the live, but that is complicated for the regular user and causes frustration.
Otherwise it is good tools for users

Pros

I think it really is a Skype for Business that has been taken to a new level. I am really surprised by the integration it has with other tools, whether or not they are from Microsoft, like Jira, Trello, among others. In addition to the very good integration that it has with MS Office and that allows such naturalness. In addition, the channels where you can customize the tabs according to the content that is shared with the specific team is magnificent, having tabs with a Power BI dashboard for the specific team is wonderful and without having to leave the application.

Cons

Although I feel like a lot of Skype features were rescued, I miss a few others. The meeting notes cannot be taken directly to Onenote as it could be done with Skype, I miss the surveys that could be done during the meeting, as far as I can remember now. It happens to me with the "team sites" that sometimes I want to make them specific to an existing sharepoint and associate it with a particular team, but the team site is generated in parallel. The last thing that bothers me a bit, is in viewer mode I feel that the projections look very small and even when placing the full screen mode the presentations do not cover the entire screen of my computer.

Pros

Integration with the rest of the MS ecosystem is the biggest thing Teams has going for it. It allows easy chat/calls from Outlook and the like.

The support was pretty good, as it should be from a multi billion dollar company, and usually found the problem eventually.

Cons

As with all Office 365 software, it always seems like adding new features comes before bug fixes. We used the calling feature as our office phone system, and rarely a week went by without something not working right. The most common issue was when you tried to pick up the call, it just wouldn't, or if it did, you couldn't hear the other side. They may or may not have been able to hear you, so we ended up having to tell the customer, who we didn't know if they could hear us, that we were going to transfer them to another agent. Once transferred it was usually fine, and we were able to transfer them back to the first rep. Very annoying.

Other issues had to do with settings seemingly randomly changing. After spending hours on the phone with their support running Powershell commands, we would often discover a setting that was supposed to be set one way, but had somehow changed overnight. No one was in there mucking around all the time, but settings still changed.

Then there was the random crashes.

Pros

Microsoft Teams is a very user friendly application with plenty of features in it. The feature that I mostly been using are the Calendar where I schedule all my daily meetings so quickly and the Team groups where I use to collaborate with my team members and post any announcements. Along with that, the most liked feature is the Search bar where I can search for not only users and messages but also files. One other major impactful feature is the SharePoint and Microsoft Stream integrations, were in all the call recordings are being stored automatically which is almost required for me all the time.

Having experienced, the meeting and the call quality was absolutely great with desired options like sharing screen, call recording, audio and video device setting options along with the Meeting notes added to it, making it more successful.

Cons

Though the Teams application doesn't have any major dislikes of any feature, rather it can have improvements in user interface likely having more templates, chat background images or color, though it has three background template options. It can also have voice message option, since I felt that's the only feature missing out here, were in now we can send voice message only when there is an unsuccessful call attempt.

Also, any updates that are done being in background, which is otherwise a good thing, but that makes less visibility to any new feature or improvement added unless or until seen. So, I would suggest to have update notes or after the update just an automatic tour on the improvements.
