Verdict
The clearest difference is rating: E at 1.8 against SIGMA LINK's 1.5. E also leads on review sentiment (22% vs 9%) and ratings volume (74 vs 8). SIGMA LINK's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.
