Ok we will start with Variety shows
1.Sunny (for the fact she is called the Variety queen and she did two seasons of IY link:

2.Yuri- she has had más opportunities to mostrar off her variety talent siguiente to Sunny
3.Sooyoung- I think her talent in imitations and her "drama" voice helps
4.Yoona- her imitations are funny but not as funny as Sooyoungs
5.Taeyeon- people I think laugh at her than with her
6.Hyoyeon- same with Taeyeon
7-9 can't rank because they don't go on variety shows often
Now one a global level, I can't tell tu because there aren't any offical encuestas for that. I will reference tu to the page where I attempted to try and answer a similar question:
