You have $100 (give or take) to spend on a sealed booster box, which one are you buying and why? Are you going to keep it sealed? Open the box and the packs to then have the cards graded?
There seems to be a lot of sealed booster boxes on the market right now around $100 so thought this would be a fun discussion to get everyone’s opinion!
Japanese ultra shiny gx
If you could find one Ultra Prism and if not Forbidden Light.
Sealed WOTC 1st Edition Base set. 
Nah, probably Japanese Ultra Shiny GX as well.
Tag All stars Is probably my number one choice right now. I would keep it sealed, I almost never open boxes any more.
You can get spanish heart gold soul silver booster boxes for sub $100 which is awesome since it’s such a great set. But I already own some so it’s not my first pick.
Evolutions, Burning Shadows, or Unbroken Bonds. All are easy to find and were printed basically into the ground, but still super fun to dig for a modern card worth over $100
I would not have my heart set on any $100 English box for short term investment. If you are only buying for that reason and only have $100 to spend, at least with these sets you have the potential to pull something worth more than what you paid.
I would buy another Advent of Arceus Japanese 1st edition box. It comes with usually two zards, one shiny pokemon, and a whole bunch of gorgeous holos. Such a great set!
Definitely one of the nicer sets from the Sun & Moon era 
.
CP6 or Ultra Shiny GX
Cp6, Generations Boxes, Japanese Dpt. Buy two Keep one sealed open the other 
That was quite the sweet opening at worlds!
Cp6 is about double. Sold my last couple boxes at $200 shipped each. Current lowest BIN on ebay is $180. I would snap buy any at $100 at this point.
It would have to be All Star Tag Team to flip the cards.
