OK, computer people- which browser is the best, and why?

I’ve been using Internet Explorer for years, but I keep hearing that it’s the crappiest browser.

I need something user friendly that my “technically retarded” husband can also use easily.

Which browser, in your opinion, would be the best option for me? Why do you think your choice is the best?

I did post this in Social for the more “laid-back” guildelines, but I still need real answers. Thanks y’all!
