That's highly subjective. At our org there's a reason our baseline deployment for workstation images comes with both Chrome and Firefox. We have thousands of users across dozens of specialties (HR, logistics, scientists, engineers, etc) and they all have a multitude of web apps they use day to day. Some of those don't like Chrome or Firefox. Hell, we even had to support god damn IE11 for way too long before Microsoft thankfully forced its death by discontinuing security support (our cybersecurity people ban anything that doesn't have active vendor support with very few exceptions).

Unfortunately, I have to manage Apple devices. Also unfortunately, Verizon has yet to answer my automated enrollment requests.
