Verdict

The call

The clearest difference is review sentiment: PowerVision 4 at 78% against EXO's 16%. PowerVision 4 also leads on rating (4.9 vs 1.8) and update cadence (monthly vs every 4 months). EXO's advantage is in-app purchases (none vs 8) and iOS requirement (13 vs 15.0). On price, ads and device support there is nothing between them.
