I've found that when it comes to problem-solving, using Cursor IDE with Claude 3.5 Sonnet tends to be more accurate. However, in some cases, I still need to use 3.7.

Simulating a complex system requires me to switch between different branches, which isn’t exactly easy to manage.

That said, when it comes to modifying legacy projects, I’m really not inclined to manually go through everything without AI—especially when the mock data is complex and difficult to simulate.

We have to believe that every problem can be solved; it's just a matter of time.
