Need advice! AP Volcano v Hublot DMA11

[m-abz-t]

I was hoping to sell one my watches due to financial reasons... the two I am thinking about is the Hublot Big Bang DMA11 Maradona Spec or the AP Royal Oak Offshore Volcano Spec.

Both similar prices I believe, ideally I was thinking of holding onto the AP but just thinking with the Mardona it is limited addition (out of 500 made) but is it actually going to hold value later on? Hmmmmm

I wanted to keep hold of at least one of them so I can pass it on to my kids in near future.

What would you do? Any advice or recommendations will be much appreciated.
