PyTorch vs TensorFlow 2025: Which one wins after 72 hours?

### Data loaders - **PyTorch:** `DataLoader` is still the GOAT. It’s just Python you can `print()` inside it, throw in breakpoints, even write cursed one-liners if you’re that kind of developer. Debugging a bad batch feels almost… normal. - **TensorFlow:** `tf.data` is powerful, but it’s like dealing with a strict parent efficient, but unforgiving. The moment you chain `.map().shuffle().prefetch()` wrong, you’re staring at an error message that looks like the Elden Ring death screen.
