Would you guys choose an oc over Sebastian?

This is my persona Keko, his main design looks like the second image, but I made two!! Expendable and experiment, both images are WIP bc the second image is going to have another character added (my friend) the first image is a koi fish, ik it might not fit pressures theme but I love it so…ANYWAY. My question is, some of you really like Sebastian and his design! So, would you ever pick someone’s OC over him? Based off of looks and character arc etc, ofc coming from me I would, but! I’d like to hear y’all’s opinions! Some people are die hard for Sebastian, and others aren’t! LMK what you think of Keko!
