Shimmering Blight Or Bleeding Willow For "spam E" Attacks?

[GlacierH20]

Bleeding willow looks cooler, and is more fluid when you spam e. However, shimmering blight seems to do a little bit more damage, but has that pause at the end of the spam E combo that bugs me. Which one do you prefer, and which one should I keep on my Orthos P?

 

(Also I dont care about it matching the polarity.)

bleeding willow for me. that fourth attack in the spam combo is pretty cool
