If your AXE300 is actually handling everything without issues, then agreed - there's no point spending money. That said, the earlier answers are conflating two separate things a bit. WiFi 6E won't get you faster speeds from your ISP, sure, but the real benefit people miss is that newer routers handle more simultaneous connections way better, which matters if you've got multiple devices streaming, working, or gaming at once - not just raw throughput. The speed ceiling from your fiber isn't the main reason to upgrade; it's whether your current setup starts struggling when you add another person on a call or stream while someone else is gaming. Test it under actual load for a week before deciding, because that's what'll tell you if it's time to move on.
