If there are ingredients other than cream and possibly salt, it ain't butter. Ditch the Country Crock and just pick up some of the real stuff. It is sold in 1 lb bricks (often quartered), and is dirt cheap.
Oh yeah, and about how much butter is too much...basically, grass-fed vs. conventional butter has the same issues as grass-fed vs. conventional beef. So, there is a bit more of the not so good stuff (omega 6's), a bit less of the good stuff (like CLA), but is still much better for you than the vast majority of the alternatives.
