Aging a cigar can become complicated by air exchange. If you have a good humidor with tight seals then cello on or off is your preference but I agree that I nick cigars or resting no cello cigars with those that have cello I nick cigars.

If you have a coolidor then depending on your setup, you may have more air exchange and keeping cigars in cello slows the air exchange down.

Air exchange can start the gradual process of removing the aroma from the cigar and this will be a preference thing. Personally I leave the cello on and cigars at even 5 years of age smell fantastic pulling them out of the cello vs my cigars with no cello smell bland. Once lit I don't notice too much of a difference but I don't claim to have a great palate and I do like my Nicaraguans to temper down a bit but that is just me.
