Verdict
The clearest difference is review sentiment: ShockLink at 100% against iSpyMobile's 32%. ShockLink also leads on rating (4.8 vs 2.8) and monetization model (free vs freemium). iSpyMobile's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (30 vs 5). On price, ads, in-app purchases and device support there is nothing between them.
