Although I am leaning toward MS in majority of solutions, Teams are proving to be objectively a very serious platform preferred by majority of universities and with this option of adding custom code, there is a strong possibility that we can use this both in the combination with our courses and withing ConfTech as as new playground. As far as I can see, this will be the future strategy for platforms as the need for integrations skyrocket. The biggest drawback is that you are giving more and more to Microsoft.
