>>88155386Kizuna Ai was and still is the GOAT of the golden era of vtubing. The age of the three greats is over but no one vtuber has captured the moment quite like her. The closest that ever came to it was Gura during the silver era but she's not deserving of the title today in the copper era.
Gura has the numbers but she has very little legitimacy due to tummy hort. Ironmouse has the numbers and is more legitimate for the whole of vtubing but at the same time her sub begging undermines any claim to the title (a similar thing happens with all Hololive talents since they incestuously share views and subs).
If being the GOAT was only about views and subs then Cookieswirlc is the GOAT since neither Gura or Mouse can beat her with their sub counts combined. Being the GOAT is about bridging the gap across fandoms and representing the hobby as a whole which neither of them really do outside of their fandoms. I expect that an indie will be the one to take the mantle in a couple of years seeing how corpos have been taking massive Ls this past year.
