One "multi" sprites or multi "single" sprites

what is better have one sprite with diferent animations or diferent sprites with each character?

I say that because my characters are classified in multi sprites: enemies... which are more or less equal, and I can select anyone with an id variable...

So what do you think?

depends on the general behavior / variables / coding of the different characters.

if they all have the same behavior / variables / coding one sprite meight be easier.

if they become different (probably later) single sprites for the different characters is more flexible.

you can also group many sprites to families.
