Verdict

The call

The clearest difference is rating: a&o Hostels at 4.6 against KVB's 2.3. a&o Hostels also leads on update cadence (every 9 days vs every 2 months) and ratings volume (109 vs 4). KVB's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, in-app purchases and device support there is nothing between them.
