I'm conflicted honestly. I find with dynamic languages it's easier to just spin your wheels and move quickly in the hole you are in.
With typed languages its easy to feel you are making less progress because the feedback loop can be longer, but generally the pieces you build are more likely to work correctly.
For me Haskell and ghci repl gives good properties from both areas, especially with something like Rapid for keeping state over repl reloads.
