Sound and music aside, which one blessed your eyes the most? A few come to mind for me. A friendly reminder all Aesthetics are different, and some people may not find the MVs you do as pleasing. 
Black Pink Ddu-Du-Ddu-Du
I really love the flower aesthetic (and every other part of it really) The wisteria scene.. iconic
Jennie - Solo
Agian, Flowers. I don't even need to really explain this lol
Pretty much every BP MV LOL
Senorita - (G)I-DLE
This whole MV, the set, the color saturation, costumes, hairstyles it's just all so pleasing to my eye
Dreamcatcher - Boca (And every other MV, realistically)
Dreamcatcher is one of those groups that has the best MV. I can't get over the theatrical production. And it has a scene with multiple flowers so of course I love it.
I like snakes. I also love the colors
Oh! GG - Lil' Touch
Everything about this MV, from the foliage to the snakes is just gorgeous. The girls also look amazing. The set. *chefkiss* It feels so sophisticated
For BTS there are so many too many actually to list lol
For SHINee, I'll just post a few of my favorites, talking about them would be way too long
There are tons more but I'll leave it at that LOL
