Verdict
The clearest difference is ads: Koga Browser at none against Vision Viewer's shown. Koga Browser also leads on update cadence (daily vs every 3 weeks). Vision Viewer's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price and in-app purchases there is nothing between them.
