Verdict
The clearest difference is review sentiment: RepSpeed at 83% against VBTgo's 0%. RepSpeed also leads on rating (4.5 vs 1.0) and update cadence (every 2 weeks vs every 2 months). VBTgo's advantage is monetization model (free vs freemium). On price, ads, in-app purchases and device support there is nothing between them.
