Verdict

The call

The clearest difference is rating: Go Challenger at 4.7 against Light GO 19x's 3.7. Go Challenger also leads on update cadence (every 5 weeks vs every 3 months). Light GO 19x's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.
