I would say that OpenAI's GPT-5 (not sure which exact model) has much more amateurish design taste than Anthropic's Claude Opus model. GPT-5 can't seem to understand and move towards specific aesthetics, everything comes out looking like bootstrap.

🚨 UPDATE: After humiliating the U.S. on the world stage, Trump just jetted off to Florida—to golf.

He’s now spent 35% of his presidency on vacation, burning through $20M+ in taxpayer dollars. The laziest "president" in U.S. history.
