I voted "other" because there is no single answer.
I have trimmed cards in my collection that are rarities in any condition, so I am just happy to have them
I once danced with the devil and bought from PWCC. The PSA 7 card was trimmed and I sent it back and fought for a refund (they were not cooperative). That one wasn't worth keeping even though it was rare. I suppose for me it is all about what I bought. If I bought a PSA 7 and it is trimmed, I got ripped off. I paid a premium for PSA's eye and if they screwed it up, I don't want the card.
