Verdict
The clearest difference is price: Panels at Free against Letter²'s $0.99. Panels also leads on review sentiment (75% vs 58%). Letter²'s advantage is ads (none vs shown) and update cadence (every 2 months vs every 20 months). On in-app purchases and device support there is nothing between them.
