As people always say variety is the spice of life. Does this adage hold true when applied to world of shaving?

My question: is there anything wrong with say using a DE razor from time to time?

I ask because it is my understanding there is a period of time the face needs to adjust to a straight razor. Are the changes that occur to ones face the same that would occur if you used a DE. Should I Just expand my straight razor collection and get my need for variety satisfied that way?
