Verdict
The clearest difference is in-app purchases: MDViewer at none against Python Coding's 3. MDViewer also leads on ads (none vs shown) and review sentiment (100% vs 71%). Python Coding's advantage is chart position (#38 vs unranked). On price, device support and iOS requirement there is nothing between them.
