You can compare both lenses iso charts on Bryans reviews.
About the AF of the 50mm, I think it's pretty ok, but manual focus isn't really usable due the small and cheap construction and the sound it makes and turning it does while auto-focussing might give you the idea it's very slow.
If image-quality is a major concern, the 50 1.8 will win hands down, but for creativity I would personally buy a lensbaby before buying a 50mm 1.8.
Good luck saving and hopefully we'll see some nice pictures from you later on, or perhaps now? [A]
