I'd say Teams is NOT a chat tool. You can find on the web many pieces of critique towards Teams as a chat tool and most of them have a lot of merit to them.
Teams is good at what it does and serves its niche well, however unless your daily matters are not well aligned with the particular framework Teams is designed for expect significant friction. It's not really the team size that matters, but rather how you structure your daily work.
A lot of the power of teams comes from integration with Active Directory, Sharepoint and Office. Sharing a presentation in a meeting that viewers can browse (e.g. to check back on something in a previous slide), calendar syncing with scheduling assistant, meetings scheduled in a team, meeting recordings and recaps, linking directly to a single page in OneNote, etc. are all quite powerful features, but most of the power is relevant if your organizational matters are structured more or less as a traditional enterprise and around AD/Office.
Inviting third parties or contractors can be quite a pain, especially if chat history is relevant. Meetings having their own chat can create information searchability issues. Integrating with third party tools is less straightforward and consequentially ecosystem of integrations is a bit of wasteland.
