Verdict
The clearest difference is in-app purchases: ApprovalSignSec at none against TIFF Viewer's 1. ApprovalSignSec also leads on ads (none vs shown) and iOS requirement (14 vs 17.0). TIFF Viewer's advantage is update cadence (every 10 days vs every 2 months). On price and device support there is nothing between them.
