Not too familiar with digital scopes.
Do these digital scopes still have erector tubes in them? or are they electronically adjusting the POA?
Reason I asked is that one of the problems with conventional scopes (erector tubes/turret) holding zero is that you are dependent on springs and mechanical means to hold zero. I know some of the more expensive scopes are almost bullet proof...but sooner or later...
Not to say electronics are better and won't fail. I think a properly designed electronic aiming system has the potential to be more robust than most erector tubes/turret design.
