Verdict
The clearest difference is price: OctaLab at Free against Pixel Resizer's $2.99. OctaLab also leads on update cadence (every 4 days vs every 2 months). Pixel Resizer's advantage is chart position (#99 vs unranked) and iOS requirement (11.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
