Recommend looking up pricing on them, if you feel the investment is worth it then go for it. I don't personally have any love for Major X so I likely wouldn't slab it (but that is just me), GoCollect has 9.6 FMV at around $55, could a pressing bump it to 9.8? Then it MIGHT be worth it, but does it have staying power in the market is also a valid question?
Out of the others the only one that shows FMV raw above $100 is possibly Naomi (I just did a quick GoCollect search to be honest) and that all depends on condition.
You also have to determine are these for you to sell or keep? If you are selling then look at the best return in what you have paid, only you can really decide that. Might also recommend popping anything you are on the fence about the condition in the Hey Buddy Spare a Grade forum. You might be able to get an idea if they would be better serve selling raw instead of slabbing or even pressing to get a chance at a 9.8.
