Verdict
The clearest difference is in-app purchases: PDF Compressor at none against CollectAll's 7. PDF Compressor also leads on update cadence (every 6 days vs fortnightly). CollectAll's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
