My top to bottom on Sirlin boxes in my Sirlin collection:
Codex Deluxe - As it doesn't fit on my shelf, it's sitting sideways on top of the shelf, with the back facing the room, so it makes for a big art showpiece.
Flash Duel 2nd Edition - Its a great size, feels great cardboard wise, is just non-blivand enough to hang out among the rest of the box arts top shelf.
Yomi First Edition and Yomi Second Edition - Boxes are in good condition. The tuck boxes I still have from First Edition range from worn to new, but they're still overall nice. And Yomi Second Edition has the great box fart. Due to one of my friend's not being a fan of Yomi's character designs, it doesn't get proudly displayed like the above two.
Pandante Light and Shadows Expansion - Its like a Blivand Flash Dual box.
Puzzle Strike Shadows, Pandante Deluxe - These two have gotten really worned out. Puzzle Strike just due to the nature of it being carried around. Pandante Deluxe out of the shipping box has its leather peeling, and the magnets never worked as I would've liked (I need to keep it closed with elastic bands) The trays inside are fantastically modular which is a big plus.
Puzzle Strike 1st edition - has seen better ways, given it has both the original MDP board chips and the compensation wood chips Sirlin gave out to make up for the bad print jobs, it's currently only held together by elastic bands (and duct tape) The wooden tray inside doesn't quite fit well enough like the 2nd Edition does.
Flash Duel Deluxe First Edition - I never owned it but bought for a friend as a gift. As much of a selling point that it's been engraved with "friggin' lasers" the wooden box itself I didn't like, like it was neat it was made of wood, but it wasn't as my mind was expecting, something like smooth polished stain wood. The cover peeled and the edges were uncomfortable to hold.
