Yesterday without much promoting Claude 4.1 gave me 10 phases, each with 5-12 tasks that could genuinely be used to kanban out a product step by step.
Claude 3.7 sonnet was effectively the same with fewer granular suggestions for programming strategies.
Gemini 2.5 gave me a one pager back with some trivial bullet points in 3 phases, no tasks at all.
o3 did the same as as Gemini, just less coherent.
Claude just has whatever the thing is for now
Now, someone will say 'add more tests'. Sure. But that's a bandaid.
I find that the 'smarter' models like Gemini and o3 output better quality code overall and if you can afford to send them the entire context in a non-agentic way .. then they'll generate something dramatically superior to the agentic code artifacts.
That said, sometimes you just want speed to proof a concept and Claude is exceptional there. Unfortunately, proof of concepts often... become productionized rather than developers taking a step back to "do it right".
