Verdict
Bookshop.org and EEPP both sit at 4.8 stars, but that hides the real split: 94% of EEPP's written reviews are positive against 57% of Bookshop.org's. Bookshop.org's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs every 4 weeks). On price, rating, ads and device support there is nothing between them.
