The clearest difference is in-app purchases: xSky at none against Galaxy Map's 13. xSky also leads on ads (none vs shown). Galaxy Map's advantage is rating (4.6 vs 4.2) and update cadence (monthly vs every 3 months). On price, review sentiment, device support and iOS requirement there is nothing between them.
