I have uploaded a few stuff from P1CO_P1CO but there are like in 3 places I can get this specific animation:

(if the link can't be used use Inspect Element from your browser and keep checking until only the video player is highlighted, then find the <div class="plyr__video-wrapper"> and inside there you will find the link on <source data-yaddayadda... src="thelink">)
(There is one exclusive variation on Skeb but let's ignore that for now)
Downloading from these three and comparing the size and resolution the Pixiv version "looks like" the best version...but I use an extension for videos/gif on that so that can't be trusted (don't worry about normal images, I copy and paste the diret image link as usual)...so which one should I pick? Also what is the best way to download gif/animations on Pixiv lol.
