There's no denying that both red pandas and giant pandas are both arodable, but in the battle of cuteness, who wins? They aren't closely related species (giant pandas are bears while red pandas are more closely related to weasels), so it's not like comparing a corgi to a shibu inu.
When you're battling in cuteness scales, it's often best to compare the babies of the animals as they tend to present the most absolutely adorable version of their species. In this case, we've got two red panda twins from the Dublin Zoo against a baby giant panda girl from the Smithsonian National Zoo -but feel free to base your vote and comments on all images, videos and in-person experiences you've had with either animal.

And giant pandas are so playful:
