Same experience here, but I have some strange feeling.
Sol I'm used to working a month ago doesn't feel the same I'm using today, slower and less accurate. My gut feeling is that they quantize previous models to prioritize new ones and, who nows, make the new one look better.
Up to July I was using mostly anthropic models and the feeling was the same, so much so that I was able to predict every model release 1 or 2 days before public announcements.
and found Astra ~30% faster and at similar cost to Sol for the same outcome

the token efficiency helps Astra even though sticker price is 2.5x that of Sol
