The short answer. There isn't much data on Pantoprazole yet — 5 mentions, 1 with a clear outcome — so treat these numbers as anecdotal. It is well studied — 70 meta-analyses on PubMed.
From 5 mentions in total — the rest didn't say how it went and aren't counted.
Of the people who reported each effect, the share who said it got better.

Conclusion: Although the pooled OR of vitamin B12 deficiency was slightly increased in PPI users, but there was significant heterogeneity, and the pooled OR was too low to imply an association clearly. Better-designed prospective studies in long-term users may clarify the issue.
PubMed 37060552 ↗Conclusion: Using twice-daily PPIs is more effective in increasing efficacy increasing once-daily PPI dosage. Omeprazole and lansoprazole (30 mg) and 20 mg of esomeprazole rabeprazole are functionally equivalent.
PubMed 28964908 ↗Conclusion: was a reasonable choice, considering its moderate efficacy and safety. Vonoprazan has considerable efficacy in initial and maintained healing of grade C/D esophagitis compared with PPI, with moderate short-term and long-term safety.
PubMed 38345252 ↗Conclusion: The present meta-analysis provides quantitative estimates on clinical potency of individual PPIs that may be helpful when switching between PPIs and for assessing the cost-effectiveness of specific PPIs. However, our estimates must be viewed with caution because only a limited dose range has been tested and not exactly the same study conditions were applied for the different substances.

First-hand experiences, quoted verbatim. We show one positive and one negative where both exist.
“I was prescribed Pantoprazole (PPI) for very minor indigestion issues and ever since then my life has been ruined...that was over 8 months ago.”
“I take 40mg pantoprazole... could stand to use a PPI in phases just for the improved digestion”
