yeah WebGL definitely snappier.

I wonder though why these 3d stacks are so awful at rendering lines/meshes. Aren't they supposed to be super-optimised for this kind of anti-aliasing work? I mean even blender can be a bit dodgy sometimes on viewport mesh rendering compared with what I'm used to with SVG, even when jacking up the viewport oversampling. Is it that SVG code just spends a huge amount more time/resource on getting line-drawing perfect, whereas the 3d stacks care a lot less?
