Adapter + Canon or Original FE mount?

With more manufacturers now include FE mount option to their newer lenses, including Sigma, Tamron, Samyang, and even Tokina, is it better to get the FE version or the Canon version and use the MC-11 or Metabones to Sony mirrorless camera?

I've heard that there will be optical penalty using an adapter as opposed to using original FE mount. I've also heard focus speed penalty with adapter. Any truth to that?

I'm a Canon user but am interested in the A7 III for an upcoming trip and just to get into full frame. Getting Canon mount lenses would let me use them on both Canon and Sony bodies.

But is the penalty really detrimental that it's better to get the Sony FE version instead?
