Verdict

The call

The clearest difference is rating: DSA Master at 4.2 against Learn Java's 2.0. DSA Master also leads on update cadence (weekly vs every 3 months) and ratings volume (35 vs 1). Learn Java's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
