I like the larger storage systems, seems like a lot of real estate in which to arrange gear nicely while still being out of sight. I've tried using pelicans, but I just ended up with a random assortment of pelican cases instead of cardboard boxes. Plus I got them used, and the pick and pluck had already been picked and plucked.
Another option I had considered is a flat sterilite-type container which I could stack up somewhere. I think if lined with foam, it would keep gear reasonably organized and not rolling/sitting on top of each other.
