The clearest difference is review sentiment: Smart Dentist at 100% against STL Simple Viewer's 18%. Smart Dentist also leads on rating (4.9 vs 4.3) and ads (none vs shown). STL Simple Viewer's advantage is ratings volume (923 vs 61). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. STL Simple Viewer sells 4 in-app purchases, starting at $0.99 per 7 days and Smart Dentist sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
