The clearest difference is rating: WikEM at 4.8 against Pacemaker's 3.5. WikEM also leads on ratings volume (4.8K vs 62) and review sentiment (54% vs 38%). Pacemaker's advantage is in-app purchases (none vs 10) and iOS requirement (11.1 vs 15.1). On price, update cadence, ads and device support there is nothing between them.
