I prefer Google Chrome because you can sync it with your google account and keep your bookmarks and other stuff synced and can access it on multiple devices. When I do have problems though (but mostly my computer having problems, as in privacy errors) I use Microsoft Edge, and if that doesnt work then i go with Firefox but nothing else. I barely wanna use Firefox. When I had windows 7 and earlier i used Internet Explorer because i barely knew about Chrome and Edge never exsisted yet. But yeah, Chrome is my favorite browser and i never paid attention to how much RAM it takes up because it hasnt affected me yet.
