Have not tried a bitbox, but some issues I have with it. It requires being plugged into a computer and therefore cannot be used airgapped. It does not allow you to create your own entropy.

It appears to be focused as a discount device. Something you can get into for a low price. If that's what you want, maybe it's a good entry level device. Then again, I'm not sure a discount HW wallet is a great idea in the first place.

Perhaps I will buy one to check it out.
