Verdict
The clearest difference is in-app purchases: Stack Golf at none against Thermal Viewer's 2. Stack Golf also leads on update cadence (every 2 days vs every 5 days) and iOS requirement (12.0 vs 15.0). Thermal Viewer's advantage is device support (4 vs 2). On price and ads there is nothing between them.
