Verdict
The clearest difference is ads: Intergalactic Solar System at none against Sun Light Hours's shown. Intergalactic Solar System also leads on iOS requirement (13.0 vs 16.6). Sun Light Hours's advantage is update cadence (every 3 days vs monthly). On price, in-app purchases and device support there is nothing between them.
