Hello, what editor do you guys tend to use alot?

I've been using NotePad++ for awhile now for my landing pages but I am starting to think I want to switch. I liked Brackets but I only got to use it once because it stopped working and I was too lazy to find a fix for it because I wanted to get my landing page up and ready. Is there any with a good live preview? Like one that does it as you finish a line?
