You are going to get different answers to this question from everyone but truly it is personal preference. IF you are going to let the cigars age in the humidor than I would say take the Cello off, some people leave it on so they are easier to transport or rummage through in your humidor. Check the tons of info on this subject on the search. And no cello does not denote the quality of a cigar Its just manufac. preferance.
