Verdict
The Document Converter and Winmail Viewer both sit at 4.7 stars, but that hides the real split: 100% of Winmail Viewer's written reviews are positive against 36% of The Document Converter's. Winmail Viewer also leads on update cadence (every 9 days vs every 5 months). The Document Converter's advantage is ratings volume (6K vs 19) and iOS requirement (15.6 vs 17). On price, rating, ads and in-app purchases there is nothing between them.
