Well I was a Chrome user, but sooner than later was too heavy and failing with a lot of stuff
I remember when Chrome was first released back in 2008. I was using an old laptop that was barely running anymore. I don't remember which version of Internet Explorer it had, or even the Windows version (I think it was 98 upgraded to ME). Anyway, it would barely run IE. Chrome was initially very light, and it gave new life to the laptop. I could now browse again.
Over the years, as Chrome has developed and added features, it has indeed become much heavier. It is still my default browser though. In this day and age, the spec requirements of even the heaviest browser has become pretty much a non issue because hardware is cheap. It costs very little to add 8GB of RAM, or even an SSD.
That said, I still use IE, Edge, and Firefox occasionally, and I cannot say that I can tell any significant difference in speed between any of them. Every computer I use regularly has an SSD and
at least 8GB of RAM, so maybe I'm spoiled!
