The thing I hate most about the new version of Teams is that it flashes the taskbar when a new message is received. You can disable the pop-up notifications, but that doesn't affect the flashing taskbar for some (??) reason. The old version of Teams didn't work like this, it was possible to turn off all notifications & alerts so that you only got notified when a meeting started or somebody @'d you.
You can go into do-not-disturb mode to stop the flashing, but then pings aren't delivered and you can't do 1-on-1 calls. So there's a pretty significant tradeoff. I wasn't able to find a way to disable them any other way (registry hacks I saw recommended online didn't work).
This sucks because if I see the taskbar flashing, I MUST go and check out Teams. It's too distracting to leave on. So there can't be a background group chat where I'm not taking part and doing other things -- I get dragged into checking every message which is extremely annoying. I suspect that 'immediately check out the app causing the taskbar to flash' is basically a conditioned response for most computer users so I doubt I'm the only one who feels this way.

I also strongly dislike the vibe of the Teams emoji set. The :) looks like it's playing dumb, and it adds that connotation to messages I see from people using it. (admittedly I've only seen it be used by my dumb coworkers)
Bloomberg Terminal is a hardware/software dynamic duo!
Reuters and Dow Jones have competitive packages too.
Other software in finance:
kdb, for time-series analytics [0].
AmiBroker - amazing tech analysis package, and AmiBroker Formula Language (AFL - found this because I like J and APL), an array-based PL with debugger built-in to the AmiBroker platform. Fast [1].
I have been programming since 1978 starting on a Commodore PET 2001, but I saw computers and programming as tools. I was studying neural nets and genetic algorithms in the early 90s. I gravitated to lean, simple and easy software, but somehow every software I use just seems so bloated, in-your-face, inefficient, that I have chosen simple tools to use now. I keep a J interpreter open on my desktop along with Frink as more-than-desktop calculators. I use a Home edition of Mathematica, the orginal notebook interface, that has so much curated data and built-in functions that what was once complicated is now a great ecosystem to do math, analysis, reports, engineering, etc. And, yes, Excel, no matter how much it is disparaged by programmers. I gave up Inventor and other CAD programs for Alibre Design (yes, I have SolveSpace on my toolbar for fun!). I am so glad I steered clear of IT/SW engineering/etc. after speaking to many in all parts of the industry. The tool is their job, not the thing the tool does.
PS: I have run hundred-million-dollar construction jobs in SE Asia and MENA using WhatsApp in the field from my Samsung Note to annotate drawings, photos, etc. even though Slack and high-end PM programs were back in the office.
KDB is the epitome of finance software. Cool in theory, and a decade ago probably the right choice if you needed to separate compute/storage and just get crazy high performance, but god damn I hate actually having to deal with it. Would rather DuckDB or even just Polars every time these days.
If it is the only tool you use and you came from a world of Skype/Lync, then for you Teams is a significant improvement. But for example if you come from Slack, Teams provides an abysmal experience.
