Some people (myself included) think ungraded cards in simple (or deluxe) cardholders just look better than those in grading service slabs (although SGC and GAI holders are much more attractive than PSA holders). If you have no intention of re-selling the cards, then why not have it present the way that's most aesthetically pleasing to you (or conforming to your collection).
