So I would make two adjustments to how you have them oriented, assuming they will fit your machine.
1. Dont "Twist" them along the X and Y, keep them straight so you dont have any weird stepping in the sides due to the pixel pattern, if you do have to twist in the X and Y I would make sure you're at 45 degrees to get the least visible impact.
2. I would point the nose skyward, round shapes are hard to print in square pixels, but the best angle to get the least visible stepping is a function of layer height and XY Pixel size. This:
https://www.rc87.blog/angle-calculator/ is a helpful tool to determine the optimal slope at which to get minimal artifacting from the pixel and layer lines. For example, I print on a mono X with 50um layer height, since the pixels are also 50um, the ideal angle there is calculated as 45 degrees. Generally I print flat to the plate as most of the stuff I print is rectangular and doesn't have nice curved features that need to be smooth.
so in short, square to the build plate, slope nose high at about 45 degrees. support the bottom with lots of medium/light supports and the back wall with light supports to help them break away cleanly. If sloping at 45 makes the back wall look too unpleasant, reduce the angle a bit
