It is going to definitely differ from collector to collector. The main point is: what is your end game in your collection?

Do you want to sell it back for profit?
Do you want to customize figures?
Dioramas?
Play with them and then just let your kids have them and just kinda lose track of it?

Either way, what you want out of your collection will dictate how you treat your collection.

Example: I'm a completionist who opens up all the figures. But I'm never really that concerned with intial paint apps because what I do is I put all my figures into different boxes. I have a box that is all Avengers (past present), Villians, Mutants, Army Builders, and other (I need to buy more boxes!!! they are OVERFLOWING)

But because they are in the same box, sometimes the paint apps rubs off on to different figures. My Vision and Moon Knight's capes have speckles of different colors from just being thrown around among other figures. Now this may sound like Toy Hell to some people (HOW COULD YOU!!! VISION!!!!!!??? HE IS ONE OF THE RAREST GUYS GOING)

BUT my endgame is purely pleasure and I'm not looking to sell or even make a profit.
