Verdict
The clearest difference is rating: Obsidian at 4.5 against Compose's 3.9. Obsidian also leads on ratings volume (2.7K vs 7) and chart position (#140 vs unranked). Compose's advantage is iOS requirement (8.1 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Obsidian holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Obsidian has 2.7K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 67% of Compose's written reviews are positive against 62% of Obsidian's, so the app with the better star average is not the one people write more warmly about.
