Claude Pro ($20) vs. ChatGPT Plus ($20) for Robotics, ML/DL/RL, & Data Analysis: Which holds up better?

Hey everyone, I’m deciding between a $20/mo Claude Pro and $20/mo ChatGPT Plus subscription and want real community reviews. My primary work covers: Robotics & Systems: C++, ROS/ROS2, state machines, hardware integration. ML / DL / RL: PyTorch/TensorFlow pipelines, model implementations, RL environments. Data Analysis: Dataset wrangling, statistics, and visualization. Specifically comparing Claude (Opus/Sonnet) vs. ChatGPT (Sol/Codex) : Code & Math Accuracy: Which model writes cleaner, low-bug code for complex C++ state logic, PyTorch architectures, and RL reward functions without hallucinating APIs? Data Analysis: Which platform handles dataset analysis, pandas manipulation, and data plotting more effectively? Usage Limits & "Greediness": How fast do you hit limits during heavy multi-file refactoring or data runs? Does Claude's usage pool burn out too quickly compared to ChatGPT? Final Verdict: If you could only keep ONE $20 sub for this stack, which actually saves more time and headache?
