Verdict
The clearest difference is rating: Spell Check at 4.4 against IRS's 3.0. Spell Check also leads on review sentiment (35% vs 0%) and ratings volume (548 vs 6). IRS's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, update cadence and device support there is nothing between them.
