PSA/SGC Slabbed Photos....To Crack or Not?

[LEHR]

PSA has their own photo authentication and slabbing division and both SGC and PSA will slab cabinet photos.
It's my understanding that most large institutions (MLB Hall of Fame, Museum of Modern Art, Smithsonian, etc.) will immediately remove any slabbed items from their plastic tomb upon receipt as it's not deemed archivally safe to have these items slabbed for long term preservation/storage.

So my question is this: If you are a photo collector do you prefer your photos slabbed or raw/unslabbed? If raw/unslabbed, do you buy and crack out slabbed photos for your collection, or leave them slabbed if purchased that way?

Personally, while I like the authentication aspect I prefer my photos out of the slab. With that being said, when buying pre-slabbed photos I've only managed to bring myself crack a couple out of their tomb because I can't get past the fact that I'm most likely pissing away some of the "value" of the photo by removing it from the slab.

Thoughts?
