Verdict

The call

The clearest difference is in-app purchases: MDViewer at none against php's 6. MDViewer also leads on update cadence (every 3 days vs every 7 months) and review sentiment (100% vs 91%). php's advantage is device support (4 vs 2) and iOS requirement (14.0 vs 16.0). On price and ads there is nothing between them.
