On the fence between keeping my Ironclad CCU and finding a path to Ironclad assault

The title is pretty clear, but to be more specific I'm trying to get more opinion and get help summarize the pro and cons of both . Afaik classic as more grided cargo and a smaller ramp/something in the way to prevent the transport of nova tank and/or vehicle on the bigger side .

Assault get almost a third less grid space for cargo but as more armor and a r&r spot that will be use for ground vehicle and probably any ship small enough to put a part of it in the area .

Do I miss something obvious ? Do you think that losing grided cargo space could/will be mitigated by chaos storage (that could be pretty close to entity limit of the ship) ?

So can you guy help me on that?
