I feel like I had the best and worst ~month experience on 4.6. Initially when it came out, it seemed to ask good questions and genuinely do well on complex tasks. From about mid-March it was absolutely abysmal, it seemed to assume the stupidest answer/angle for everything and make weird mistakes. 4.7 seems decent so far but usage hurts - at some point my company switched me to standard seat and I used up 80% of my session usage in 1 prompt. I got my premium seat back since but I think pro/standard plan + opus 4.7 is unusable for daily driving.

That experience is also likely tied to the claude harness around the model, and not being as tuned right after model release. They iterate on this and different models need different words (unfortunately...).
