Verdict
The clearest difference is in-app purchases: Wordlala at none against 3D Solar System's 10. Wordlala also leads on ads (none vs shown). 3D Solar System's advantage is update cadence (fortnightly vs every 31 months). On price, device support and iOS requirement there is nothing between them.
