Rasterizer render is very interesting for objects with lot of sharp geometric details (like long vertical or horizontal lines create by shadows on a building for example).
In this case you must use more samples like Joe said.
In my project, I used a very low sampling because it was only an organic subdivided character with a very simple color and bump map.

I start with the shading samples around 2 or 3. Then I render out a test.
I then raise it up to around 6 and do a test. If I see a big difference,
and I prefer the higher level I use it (or in between). But shading
samples take a lot more time to render. So you want this as low as
possible. But if you use detailed shaders, or bumps you will see a big
difference in detail between low and high samples. Rarely do I go over 8
or so for shading samples.
Pixel samples have much less of an effect on render time. I frequently
have these at 10-30. It depends on the fine details of the model. A finely
detailed moel, like a ship with rope rigging, or a tree with leaves can
require fairly high pixel samples. With simpler geometry you could keep
pixel samples pretty low like 5-10.
Note that I am stickler for seeing NO crawlies or jaggies... So my numbers
may be biased on the high side...
