Verdict
The clearest difference is ads: Spark Mail at none against GMX's shown. Spark Mail also leads on chart position (#100 vs unranked) and update cadence (weekly vs fortnightly). GMX's advantage is review sentiment (77% vs 61%). On price, rating, in-app purchases and monetization model there is nothing between them.
