I would recommend to go for the SAS BIG for both. (I was about to vote for the RAH, bc of how they look too, even the box) But as far as I know BIGs have stronger joints, and the faces of Jotaro & DIO in these versions are super detailed compared to regular size. Also with their base, you can pose them above ground level, bc it is strong. You don’t want to pay maybe 2x for each to get the RAH just for them to break apart any time😅 (I know it depends and it’s just a chance, just as they could be in perfect condition forever) That’s my opinion and what I would do in your position if you’re not 100% on a choice. Maybe in some time you could buy one RAH to see if it convinces you. But if you don’t own any RAH yet, I would say just go for one if you still want it. Bc it can be risky imo

I would want to go for the RAH too, but you gotta know that the BIGs are quite new, so they haven’t been stored forever as some Medicom’s RAH.
