If you scale up to a 3rd account, it's just worth dedicating that to a booster (From memory a max-skilled Orca will give about a 52% improvement in yield), in which case you could switch back to Hulks and use the Orca to store the ore. But you lose the mining bonus while the Orca is hauling.
For 4 accounts or more, a booster is no-brainer.
Give me liberty or give me lasers
Orca is not even remotely worth it if you're running just one Hulk.
Use either two Mackinaws or do jetcan mining with two Hulks and one of you hauling with an Iteron or something when the cans are full. You'll want to find an empty system for that though.
I will also say two macks.
orca doesnt mine, it sits there giving bonuses.
for many miners that's good. for one miner, a second miner is better.
two macks store 70k ore. an orca stores - with rigs - about 140k ore. unless you're very far from a refinery, stay Mack.
