They work the same way and are similarly effective. The practical difference is drug interactions — pantoprazole interacts with fewer other medicines. For most people either is fine, and how you take it matters more than which you take.
Both are proton pump inhibitors. Both switch off the acid pumps in the stomach lining, and both are used for acidity, reflux and ulcers.
People often assume one must be stronger. In practice they are comparable, and a doctor's choice usually comes down to what else you are taking.
The genuinely important points are the same for both: take it before food, and do not stay on it for months without review.

When Omeprazole is usually the better choice
- It is what your doctor prescribed and it is working
- You are not on medicines that interact with it
When Pantoprazole is usually the better choice
- You take several other medicines, particularly clopidogrel after a heart procedure
- It is what your doctor prescribed and it is working
Important
Neither is meant for months of unsupervised daily use. Difficulty swallowing, vomiting blood, black stools or unexplained weight loss need investigation, not stronger acidity tablets. And chest pain should never be assumed to be acidity.
