In terms of the number of samples per pixel, the largest the number of samples there are, the slower the speed is (the more computationally intesive it is) and the higher the antialiasing power is. For pixel sampling, nearest pixel sampling is faster but less powerful in antialiasing, and bilinear sampling is slower but more powerful in antialiasing. In level sampling, the lower the level is, the larger the map is. This means the lower the level, more space it takes up, the more defined the image is, and the lower the power of antialiasing is.

Below is the the image of a fractal computed using 4 different filter combinations. From top to bottom, the filter combinations are level zero and nearest pixel sampling, level zero and bilinear pixel sampling, nearest level and nearest pixel sampling, and nearest level and bilinear pixel sampling.
