Stackwax is the shelf for DJs. You hear a track. You need the BPM, the key, the Camelot code. You need it in your library before the night is over. You want to buy it on vinyl. StackWax does all of it in one tap. Hold your phone up. StackWax identifies the track, detects the BPM and key in real time, gives you the Camelot code, and shelves it directly into your library. Then the library works for you. Sort by BPM, by key, by Camelot. Drag tracks into playing order and sketch your next set before you step behind the decks. When you find something you want on vinyl, tap through to the Discogs listing and buy it without leaving the app. Connect your existing Discogs collection and import your records.

Verdict
The clearest difference is in-app purchases: Echos. at none against Stackwax's 3. Stackwax's advantage is update cadence (every 5 days vs every 2 months) and iOS requirement (15.0 vs 18.6). On price, review sentiment, ads and device support there is nothing between them.
