I've had the opposite experience. See this example scene:

// 100% pixel perfect without antialiasing
// +w160 +h120 -a

// 100% pixel perfect with antialiasing method 1
// +w160 +h120 +a0.1 +am1 +r6

// very small bleed with with antialiasing method 2
// +w160 +h120 +a0.1 +am2 +r6

#declare W = image_width;
#declare H = image_height;
camera {
   orthographic
   location -100*z
   right W*x
   up H*y
}
#default {finish {ambient 1 diffuse 0}}
plane {-z,0 pigment {checker rgb 0, rgb 1 scale 5}}
sphere {-30*x, 20 pigment {red 1}}
box {-20,20 translate 30*x pigment {blue 1}}
