Verdict
The clearest difference is update cadence: Inside Earth at fortnightly against Earth's Core's every 70 months. Inside Earth also leads on rating (4.7 vs 4.3) and ratings volume (48 vs 4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Inside Earth holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Inside Earth has 48 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
