Verdict
The clearest difference is review sentiment: Node.js Lab at 63% against STL File Viewer Pro's 10%. Node.js Lab also leads on iOS requirement (13.0 vs 16.6). STL File Viewer Pro's advantage is rating (4.5 vs 3.9) and update cadence (fortnightly vs every 5 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.
