One user noted, "The initial setup was very easy," which contributes to a smoother onboarding experience compared to GrowthBook.
- **Users say** that while GrowthBook offers a straightforward approach for those familiar with A/B testing tools, it may not be as intuitive for newcomers. Reviewers mentioned that it works well for data analysis but lacks the same level of ease in initial implementation as Optimizely.
