The creams take the hair to skin level, similar to shaving. The one I tried did not get me as smooth as a good razor. If you have a shadow with a razor blade, you will have a shadow with the cream. It also takes more time than a razor, and you have to wait several days between uses for your skin to recover. So if the object is to be hair and shadow free, the creams will not do it.
If you are occasionally without bathroom access, I would suggest an electric.
