That's nice. So similar to how a regular exchange pays for your withdrawal transaction. (And of course if it's better or worse depends on how much they'll charge).
One advantage is that your funds are already in a lightning channel, so you can immediately use it for payments within the lightning network with very low fees (vs having to pay onchain fees).

You do need to pay to both open and close a channel, so you'll incur two transaction fees in contrast to one with a regular exchange.
Sparkswap opens the channel to the user, so Sparkswap will incur the channel opening and closing fee.
