They all spray about the same, but could use a cleaning like you said.
I have some small drills to clean the holes.
I will enlarge the one hole that is pointing up when the wipers are at the end of their first cross sweep. The holes appear to be about .030. I think I will enlarge it to .037.
Maybe this will add washer fluid where needed,
