Verdict

The call

The clearest difference is rating: Textkiller at 4.3 against IRS's 3.0. Textkiller also leads on review sentiment (37% vs 0%) and ratings volume (13K vs 6). IRS's advantage is in-app purchases (none vs 16) and iOS requirement (10.0 vs 15.0). On price, ads and device support there is nothing between them.
