Verdict
The clearest difference is in-app purchases: APCSP at none against C/C++ LLVM Clang's 7. APCSP also leads on review sentiment (100% vs 85%). C/C++ LLVM Clang's advantage is update cadence (every 2 months vs every 7 months). On price, ads, device support and iOS requirement there is nothing between them.
