Verdict

The call

The clearest difference is in-app purchases: Sol Explorer at none against Galaxy Map's 13. Sol Explorer also leads on ads (none vs shown) and rating (5.0 vs 4.6). Galaxy Map's advantage is update cadence (monthly vs every 171 months) and ratings volume (609 vs 6). On price, device support and iOS requirement there is nothing between them.
