Verdict
The clearest difference is review sentiment: Galaxy Map at 80% against X's 0%. Galaxy Map also leads on rating (4.6 vs 1.3) and ratings volume (609 vs 3). X's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
