Verdict
The clearest difference is price: CSVReader at Free against EML Viewer's $1.99. CSVReader also leads on rating (4.6 vs 3.0) and review sentiment (60% vs 49%). EML Viewer's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence and device support there is nothing between them.
