This take rings true for me after admittedly only a couple of hours of use of gpt-5. I had an issue I had been working with Claude on but it was difficult to give it real-time feedback so it floundered. gpt-5 struggled in the same areas but after about $2 of tokens it did fix the issue. It was far from a 1 shot like I might have expected from the hype, but it did get the job in about an hour done where Claude could not in 3.

For reference my Claude usage was mostly Sonnet, but with consulting from Opus.
