The clearest difference is review sentiment: Comet at 65% against Google Smart Lock's 10%. Comet also leads on rating (4.8 vs 2.5) and update cadence (weekly vs every 2 months). Google Smart Lock's advantage is in-app purchases (none vs 3) and chart position (#178 vs unranked). On price, ads, monetization model and device support there is nothing between them.
