Much worse.
If you had done this correctly, you can take a set of drives
from a working mdadm system and bring them to another computer
and use mdadm to import them and use them. Depending on which
options you chose and which drives you brought over, you could
potentially do this with fewer drives than "all".
(The same is true of ZFS and BTRFS.)
On every hardware RAID system that I know of, you need the same
hardware RAID on the receiving system -- sometimes just a
compatible card, sometimes precisely the same card.
