Resolved Which is better, a sprite mask or multiple sprites

Which will be more optimized, using a sprite mask or multiple sprites? Let's say I have 2 sprites. Asphalt and grass and it is necessary that in some place, in the middle of the grass there was asphalt.
Is it better to make a sprite mask for grass or to bypass this area with several grass sprites?

 

if the grass is all batched in the same drawcall multiple sprites will be better

also depends if you use many game objects instead of only 1

1 game object better than many
