Verdict
The clearest difference is rating: A Solar System Journey at 4.5 against BlackHolesHD's 3.4. A Solar System Journey also leads on ratings volume (434 vs 41). BlackHolesHD's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
A Solar System Journey holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: A Solar System Journey has 434 ratings behind it against 41, so its average is the more settled of the two. Written reviews complicate that: 26% of A Solar System Journey's written reviews are positive against 27% of BlackHolesHD's, so the app with the better star average is not the one people write more warmly about.
