Verdict

The call

The clearest difference is rating: 减论 at 5.0 against 知乎's 4.5. 减论 also leads on in-app purchases (none vs 10) and ads (none vs shown). 知乎's advantage is ratings volume (26K vs 1) and update cadence (weekly vs every 3 weeks). On price and device support there is nothing between them.
