Well, just checked their brochure:

The Leaf can be driven purely single pedal, or “one pedal” as it’s known. The Kona can’t. Well, let me amend that: the Kona can be driven one pedal for the most part, but not entirely. The Leaf comes to a full stop if you lift off the accelerator – the Kona doesn’t. The Kona will slow down if you lift, more so than what you might know from engine braking (depending on regeneration setting), but it will not come to a stop. I don’t think it would matter for hand controls, since it’s basically the same concept – the Leaf still does have a brake pedal of course, it just slows down faster than “normal” cars if you let off the accelerator.
Genuinely, if we leave “design” out of the picture (which is ironic since that’s, to me, the one downside of the Kona, i think it’s ugly both in and out – at least the EV), the Kona is by far the smartest choice on the scheme currently, if you can make the charging work (charge at home, reliable charger close by etc). Maybe not for the heart, but definitely for the wallet, the brain and really, the mind, since it just is a trooper and you can trust in the range.
