Quick read

Optimus Gen 2 leads on more comparable public fields than Walker. This is not a blanket verdict: missing values are treated as not sourceable, and Reality Score/lifecycle should be read alongside the spec rows. Public specs are sparse, so avoid over-reading the head-to-head.

Walker

No automatic spec wins from sourceable comparable values.
