Verdict
The clearest difference is rating: i at 5.0 against ChmPlus Lite's 3.6. i also leads on ads (none vs shown). ChmPlus Lite's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (monthly vs every 4 months). On price, in-app purchases and device support there is nothing between them.
