Theoretically both works - the single system depth will allow you to encounter new issues / see how the stuff you developed panned out.

But that's too slow a process IMHO due to how organizations work and i wouldn't do it unless the field, you are in, is really deep to start with eg gaming/distributed computing etc. You also face the risk of being in the same rut over and over again and all of a sudden the rug could get pulled from underneath you (hopefully so that you will learn new things).

I would say stick around until you gain expertise (and actively do so) in the domain and know its problems and its typical solutions and then move on 3-4 yrs ?

I was shoved around due to market forces ... its the best thing that happened to me IMHO
