I have the same impression. It is less verbose and doesn't beat around the bush (unlike GPT-3.5/4.5-Turbo), provides almost the same quality of code for the test cases I have, and has similar (GPT-4) or much better (GPT-3.5) spatial comprehension. It is at the GPT-3.5 level of math (read it as not good enough but better than anything else).
