Verdict
The clearest difference is in-app purchases: Digital Stack at none against Signal's 1. Digital Stack also leads on review sentiment (100% vs 68%). Signal's advantage is update cadence (weekly vs every 3 weeks) and chart position (#11 vs unranked). On price, ads, monetization model and device support there is nothing between them.
