Depends on if you prefer the aesthetic over the protection. As others have said, both PSA and SGC have tons of cards that noticeably "bounce" around inside their slabs. Now, unless you are routinely using your slabs as air hockey pucks it may be hard to actually damage cards this way - but still I have never liked the look of "movement" in a slab, or the thought that even if slight and extremely gradual - I am somehow further damaging cards in slabs like that by handling them at all.

While the BVG sleeve will prevent this particular issue, I would agree that the materials they use are cheap, older slabs generally get to looking like crap, and above all that is the problem that their grading is not in line with other TPG's here in the 21st century. My current vote is basically to keep still raw cards raw...
