The clearest difference is in-app purchases: Dozen at none against Ominomicon's 1. Dozen also leads on ratings volume (21 vs 2) and iOS requirement (15.0 vs 18.0). Ominomicon's advantage is update cadence (every 3 weeks vs every 5 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. Ominomicon sells 1 one-off in-app purchase. Dozen asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Dozen against 5.0 for Ominomicon. That said, the two scores are not equally well evidenced: Dozen has 21 ratings behind it against 2, so its average is the more settled of the two.
