Verdict
The clearest difference is in-app purchases: mcloudoc at none against Polaris Viewer's 1. mcloudoc also leads on ads (none vs shown) and update cadence (monthly vs every 3 months). Polaris Viewer's advantage is iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
