Verdict
The clearest difference is rating: ChatgpTop at 4.7 against PDF在线版's 3.5. ChatgpTop also leads on update cadence (every 11 days vs monthly) and ratings volume (10 vs 2). PDF在线版's advantage is in-app purchases (none vs 4) and iOS requirement (11.0 vs 17.0). On price, ads and device support there is nothing between them.
