>>43319996 said, it really is determined more by your group. I think 5e stacks things towards success better than other systems for most people. But there will be people, and groups, for which that is not true.
Generally I think the best idea is to look around your area and see what most other people are playing. To especially look at those groups you would like to join and see what they are playing. Then get that system.
