Verdict
The clearest difference is rating: Worm.is at 4.5 against Slime.io's 3.8. Worm.is also leads on ratings volume (235 vs 6) and update cadence (every 5 days vs fortnightly). Slime.io's advantage is in-app purchases (none vs 7) and iOS requirement (8.0 vs 15.6). On price, ads and device support there is nothing between them.
