Verdict
The clearest difference is review sentiment: VSim at 85% against ZKPassport's 23%. VSim also leads on rating (4.7 vs 2.9) and ratings volume (16K vs 14). ZKPassport's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and device support there is nothing between them.
