I didn't try gnuk - This is the first time I hear about it.

I was comparing NEO to other tokens I've seen and used - it's not worse, but non of them are as simple as I would like (and no, I don't know how to describe the simplicity I'm after).

Looks like the gnuk is a software implementation - do you trust it not to disclose the private key if it is physically accessible? If you do, why?

I trust the NEO to require more than what your average hacker can use at home - though, of course, I don't trust it against state actors, who probably have the fund and equipment to make any smart card apparatus "talk".
