Webex/Outlook/Teams/Zoom/Slack/Gmail - None of these are any inferior or superior to each other (maybe not at the start when the product was launched - there could be big feature/usability gap - but once they are matured which most of these - not much differentiators to matter) and literally none of these products to be used at any corporations are evaluated by their technical or usability excellence - it is simply vetoed or decided by the corporation CEO know which vendor's CEO/CFO well and what both companies agree to barter (use my product and in exchange I will use your product in my company kind of thing). For a end user in any company - unless you are super advance user or some niche feature - any of these software should just work well for day to day usage.
