This is gonna sound like a troll post but i assure you it is not.
I don’t have a coding background but I’ve used Teams in a lot of workplaces and really only encountered like 2 issues entirely.
Either I got seriously lucky or it was before enshittification.
Why do you yourself dislike it? Is it UI? Performance?
I should also say I use Teams for basic purposes like messaging and uploading files, I literally don’t touch anything else and performance hadn’t been an issue. (Likely because I’ve been given thicc-ass workstations in the past)
I just want to point out that you’ve huffed a little too much product marketing bullshit. Sure, different platforms have different capabilities but what the fuck is a collaboration platform that isn’t a communication platform.
Hell, I consider github/labs/etc to mostly just be a communication platform, most of what you’re doing is just ticket focused.
I literally use this tool on a daily basis, it works very well. I’m not spouting anything marketing related, only how I see and use it.
A communications platform allows you to talk to each other via text, voice, video.
A collaboration platform allows you to work on information together which includes things like document co-authoring(SharePoint and Office) and group task management(Planner), but can extend much further into things like Shared Pages (OneNote or Loop), Database-lite systems with Forms (SharePoint Lists, Power Apps), Workflows (Power Automate), and more.
I’d consider Slack to potentially qualify as a collaboration platform though, it integrates really well into both SharePoint and GDrive to enable shared editing - that editing isn’t baked into slack but slack does go out of its way to support it through link unfurling and document embedding.
I actually think Teams is weaker in this regard because it’s too easy to accidentally download and copy files when you’re intending to edit a shared copy (and SharePoint has some wonkiness with syncing changes in a reasonable time frame).
