Well, I willingly moved from chrome to edge about a month ago and its currently my default browser.
*For starters I love the flexibility to group tabs, and even move tabs to the side bar.
*I love the integration of Chat GPT 4 AI and Dall-E Image generator which sometimes help with searches. And yes, I still use ChatGPT and Google Bard.
*To me (Its gentle on my machine resources than Chrome)
*One interesting thing i discovered was, it prompts me for coupons when am buying stuffs on some website (suspiciously creepy). Example when buying hosting on *Namecheap, it prompts for available discount coupons and gets one that is applicable to your package
*It also comes with Splitscreen where you can put to open tabs side by side
And I am still discovering more productivity features.
