Verdict
The clearest difference is ads: Protein Viewer Pro at none against Protein Sequence Viewer's shown. Protein Sequence Viewer's advantage is update cadence (every 2 days vs every 2 weeks) and iOS requirement (13.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.
