Verdict

The call

SPF and Sunglow both sit at 4.6 stars, but that hides the real split: 76% of Sunglow's written reviews are positive against 32% of SPF's. SPF's advantage is ratings volume (5K vs 268) and chart position (#54 vs unranked). On price, rating, update cadence and ads there is nothing between them.
