Verdict
The clearest difference is in-app purchases: LispPad Go at none against Rubyist's 3. LispPad Go also leads on rating (4.9 vs 4.6) and review sentiment (96% vs 83%). Rubyist's advantage is update cadence (every 3 weeks vs every 2 months). On price, ratings volume, ads and device support there is nothing between them.
