Verdict
The clearest difference is price: BDT GSU at Free against RegEx+'s $1.99. BDT GSU also leads on iOS requirement (13.0 vs 26.0). RegEx+'s advantage is update cadence (every 4 weeks vs every 6 months) and chart position (#102 vs unranked). On ads, in-app purchases and device support there is nothing between them.
