To Open or not to Open?

I've been collection Star Wars figures for quite a while and have obtained a large number of them. Until the 6" Black Series came out, my collection was limited to 3.75" figures, all of which are still in their packages. But as I'm seeing a lot of posts in r/actionfigures I've noticed that many people have opened their Black Series figures and have them displayed out of the box.

At this point I have Nearly all of them (I'm missing the SDCC exclusives: Boba Fett & Han in Carbonite, Jabba's Throne Room, First Order Stormtrooper) in addition the only others I'm missing are the Shadow Trooper & Speeder Bike, Luke & Wampa, & the First Order Stormtrooper (I'm excluding TFA figures that have not officially been released, but have made a few brief appearances online). My point is that I have enough of them now that displaying them in packages is starting to take up a ton of space.

So that's my question, Should I open them and display or keep them unopened? What is your opinion and why?

Thanks I really appreciate the opinions!
