Verdict
The clearest difference is rating: Zen Pi at 5.0 against Google Voice's 4.3. Zen Pi also leads on iOS requirement (16.6 vs 18.0). Google Voice's advantage is update cadence (weekly vs every 7 months) and ratings volume (62K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
