My 50mm 1.8 blows the doors off even my best Canon zoom at the same focal length and f-stop. Want proof? check the images in this great Fred Miranda article.....

now the 50mm he used is the 1.4 but you'll get the idea.
Unless I haven't looked carefully enough, there are no shots of the 50mm F4 lens at f8, in the Fred Miranda comparisons. It seems to me that the differences between the 24-70 and 28-70, both set at 35mm and f2.8, are greater than any differences between the 50mm F1.4 and these two zooms at 50mm.
You would generally expect good quality primes to outperform zooms at large apertures (perhaps even knock the socks off them), but at f8 or f11 I think you might be looking at some pretty marginal differences.
