Verdict
The clearest difference is rating: SLSL Dictionary at 5.0 against The ASL App's 3.6. SLSL Dictionary also leads on review sentiment (100% vs 59%) and in-app purchases (none vs 10). The ASL App's advantage is ratings volume (850 vs 2) and iOS requirement (12.0 vs 16.0). On price, ads and device support there is nothing between them.
