Verdict
The clearest difference is ads: Sikkaji at none against Heritage Auctions's shown. Sikkaji also leads on monetization model (free vs free with in-app purchases). Heritage Auctions's advantage is review sentiment (60% vs 50%). On price, update cadence, in-app purchases and device support there is nothing between them.
