Memory usage difference should be something like an order of magnitude better with .NET.

It's not a direct comparison, because the features aren't quite the same, but the Electron Teams app uses about 10x more memory than the relatively heavy WPF Skype for Business client that it's supposed to replace.

Would be nice to get a source for this interesting claim.

But I'm far more interested by real world user facing performance metrics such as: FPS, vsync consistency, input latency and comparing cpu and gpu usage (thus allowing to infer battery usage).

Skype has been replaced by an electron app https://electronjs.org/apps/skype

Skype for Business is entirely unrelated to Skype. It's mostly a renamed version of Lync.
