Verdict

The call

The clearest difference is in-app purchases: PaperPhoneLite at none against CPU's 1. PaperPhoneLite also leads on ads (none vs shown) and update cadence (every 5 days vs fortnightly). CPU's advantage is iOS requirement (15.6 vs 17.0). On price and device support there is nothing between them.
