Is the same a vector SID than a radar departure?
I only know a couple of airports with published radar departure.
I wish all airports had them! We would save time. I hate preparing for a complex SID, briefing it with the other CM, setting the navaids... And just after take off... "Fly direct to ZZZ" or "maintain runway heading" 90% of the times.
With radar departures you just climb on runway heading and wait further instructions. So easy! I mean, It is not that I am too lazy to fly a complex SID. I love flying them, if they don't interrupt me.
In a radar departure is good to have an idea of the navaids, waypoints and airways in the area, in case the ATC request to intercept a radial or join an airway, for example.
