It's a tough call. I think for me it depends on the packaging and how it's possibly displayed. I'm mostly an open and display kinda guy, but I do have a few figures stilled sealed. I also think if you have anything older, like G1, or anything original, it's best to keep it sealed. The newer stuff is fine to open. But again it depends on the packaging and how it's displayed. One of my sealed figures is SDCC Soundwave, just because how awesome it is.
