the best I have ever owned is Arc'teryx, I have 3 of them now. They are simply high quality gear, last the longest and keep you the warmest. You get what you pay for. You have to know how to size them though is you buy online.
For a good bang for the buck, hard to beat North Face. I have a pretty beefy North Face fleece I use for work or getting dirty in since it was only $150. It is tough and will last you many years of hard use. Mountain Hardware and Marmot are also good.
I have a bunch of Burton fleeces. Generally of high quality but sometimes things like zippers fail way to soon or the stretch out funky and don't fit right. They also change their line up nearly every year.
I buy almost everything on Ebay because if you know how to size things you get really killer deals on gear. $400 fleece Arc'teryx jackets for well under $200.
