Been playing with Liquid Glass in Figma and Spline. My take?
Spline wins, easily 🙌🏻

It's incredibly realistic with stackable layers, custom shapes, and interactive magnification that feels just like Apple's. You can even simulate thickness!

#Figma light direction control is a nice touch, it is limited; it can't be stacked and doesn't work on custom shapes. I hope they improve this soon.

I will use both depending on projects but #Spline is my go to for now !
