Reviewing Claude Opus 4.5

Synopsis

Greg and James (Boring Marketer) stress-test Claude Opus 4.5 against Gemini 3 Pro live. Both build landing pages and clickable prototypes for an 'EstateClear' probate-family dashboard; they then run conversion copywriting and ad creative tests. Opus produces more refined layouts and deeper product thinking; Gemini injects clever AI features. They also demo Google's vertically integrated stack (AI Studio, Anti-Gravity, TPUs, Workspace) and a Nano Banana Pro ad-creative workflow.
