Verdict
The clearest difference is review sentiment: Valence 3D at 60% against Axiom Solver's 0%. Valence 3D also leads on ratings volume (116 vs 4) and chart position (#47 vs unranked). Axiom Solver's advantage is price (Free vs $19.99) and rating (4.5 vs 4.2). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Axiom Solver is free to download; Valence 3D costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Axiom Solver holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Valence 3D has 116 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of Axiom Solver's written reviews are positive against 60% of Valence 3D's, so the app with the better star average is not the one people write more warmly about.
