Verdict
The clearest difference is rating: Hygrometer at 4.7 against SensorBlue's 3.2. Hygrometer also leads on ratings volume (6.1K vs 14) and chart position (#157 vs unranked). SensorBlue's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.
