yes the formfactor is much better,
you would better think of it as a wallet
which you can give completely to another user !
with a card i never thought of this feature, but now it looks different.
the use of key pairs is better then using eCash in an offline way
because eCash you can just copy !

but with keys you can sign any event on the LN server and you cant easily copy the chip

thats the point... i could use a ntag 213 and just put ecash on the chip
but we know the trade offs right ?
