will that message be equal with the message from armory?

It's not the "message"... but the "signature" that you need to worry about... and chances are that the signature created for an identical message in a different wallet will actually be different (sometimes even if you sign the same message twice in the same wallet) due to the "random nonce" used when creating the signatures.

Message signed in Armory:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
HCP Test signing a message in Armory and Electrum
Date: 2020/08/20
-----BEGIN SIGNATURE-----
1FFv3G8N1XLGrYcz1QeU8tA4KPCzWGjAJh
G1kswQr0+uoeNYWwb8wxz4tiGSjpU8R+VGxldtdxrNckM0YYe4Pm9u8F+sKvm3iAJCQGUvL4hQejAEyw6xx+f9M=
-----END BITCOIN SIGNED MESSAGE-----

Identical message signed in Electrum with identical address/private key, but results in different signature

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
HCP Test signing a message in Armory and Electrum
Date: 2020/08/20
-----BEGIN SIGNATURE-----
1FFv3G8N1XLGrYcz1QeU8tA4KPCzWGjAJh
HEguJMI9sQVEIDwR80pMzSq4GetnE5eaRGCOUDhPPv+ZS8JmwGicbHHH04qtVdPBTHFI3rKL/qvJcLwCe4xlM84=
-----END BITCOIN SIGNED MESSAGE-----

However, even though the signatures will be different, anyone will be able to verify that it was signed by that address/private key
