Verdict
The clearest difference is review sentiment: Previews Creator at 100% against SEM's 38%. Previews Creator also leads on rating (5.0 vs 3.4). SEM's advantage is in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
