Most 5* looking 4* and inside out

Don't know if the subject has already been discussed around here but I just got the idea and wanted to share thoughts about it, who do you feel like is (are) the most 5* looking 4* and 4* looking 5* ? (Mostly based on design, leaving out bursts is more fair)

Imo, Ningguang, Beidou and Rosaria are 5* looking

while Albedo, Kazuha and Yoimiya are kinda 4* looking
