Verdict
The clearest difference is in-app purchases: PDF Pro AI Editor at none against Chat PDF Summary's 6. PDF Pro AI Editor also leads on update cadence (daily vs every 8 months). Chat PDF Summary's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
