Verdict
The clearest difference is price: SLSL Dictionary at Free against ASL Dictionary's $4.99. SLSL Dictionary also leads on update cadence (every 2 weeks vs every 5 months) and rating (5.0 vs 4.7). ASL Dictionary's advantage is ratings volume (1.3K vs 2) and chart position (#160 vs unranked). On ads, in-app purchases and device support there is nothing between them.
