Verdict
The clearest difference is in-app purchases: Proteus Smart Display at none against VOS's 2. Proteus Smart Display also leads on iOS requirement (11.0 vs 16.4). VOS's advantage is update cadence (every 3 days vs every 3 months). On price, ads and device support there is nothing between them.
