Today, Im participating in my first-ever WFMW! And wouldn't ya know it's the backwards edition?

So my question to you is this:
What brand of paint is your favorite? I painted my first room a few months ago and apparently bought a really bad paint. It has taken four coats so far and it still needs another! I gave up though and just left it as is. So now that I'm about to start painting the bedrooms, I need some help.
If money wasn't an issue, what brand would be your definite choice? And also, when money IS an issue, what brand(s) do you find still work great?
