Stepper motor 0.9° vs 1.8°

When choosing a stepper motor for a 3D printer, is it better to have a smaller step angle?
Now I have two options:
1. [www.oyostepper.de]
2. [www.oyostepper.de]
Obviously, a stepper motor with a step angle of 1.8° is cheaper, so what are the advantages of a motor with a small step angle? Should I choose a more expensive stepper motor with a step angle of 0.9°?

Don't bother with 0.9's unless you have a delta 3d printer

For other printers it just doubles the number of steps it needs and halves the maximum speed

0.9 steppers are more precise leading to less VFAs on your prints surface. Their main drawback is they reach slower speeds with the same configuration as 1.8 steppers (roughly half of theirs).

It may be beneficial if you print fast and/or are very keen on maxing out your print surface quality.or when you use large pulleys (which translate precision to speed themselves) for some reason.
