Debugging with Developer is much faster than the Eclipse Designer. Also the overall work flow with Developer is faster even though Designer is similar in terms of UI. I think Designer will become better with time but as it is at the moment it needs more work imo.
I hope they keep developer usable (version updated) for a while during this transition, even without official support.
