Just wondering if anyone has experience with the three. I have used read through some RoR and used Django. They seem fairly easy to use. Is lift \"easy\" like these two are?
If ease of start up is your only concern then you may want to go with RoR or Django. But if long term performance, scalability and maintainability are significant, if you are capable of learning scala, which is a bit more complicated but quite elegant and enjoyable in my experience, then Lift or Play will probably yield greater longevity and adaptability long term, which may greatly out weigh the slightly larger startup time on a significant project. Take a look at some of the performance comparisons
