I think it's an apples-to-oranges comparison because the techniques and tricks for making MVs are so much more advanced nowadays. See, for example, the CGI in Zimzalabim or the dance scene transitions in Superhuman.
The SNSD MVs are mostly dance-centered, with Sailing being the outlier.
As several others have mentioned, Red Velvet MVs have a lot more variety and weirdness. And they range from 0% dancing (OOTN, I Just) to 100% dancing (Be Natural).
