Frankly, you're not missing out on much.

The new biz kits are almost identical inside (replace AdP with ESPA) but with an uglier case outside.
Some box versions are less practical as combs/shavers/proper toothbrushes no longer fit into them.

The new first kits are frustratingly large, and good luck trying to fold your pyjamas back into that case if you plan to wear inflight + keep them.

My personal opinion is that the 'Etihad' brand stamping on the amenity kits makes them look cheaper than they probably intended them to be.

At least they're moving forward. Could have taken few ideas from Emirates...
