A trained thief skilled in infiltration and combat vs a child who fell into a TV.

Kay.

Joker.

Well Narukami has more experience?

True, from that i think Narukami would win

But the pt are more naturally skilled in the art of combat imo.

I hate to betray you, but Izanagi is cooler than Arsene.

I think Joker would win in this situation. His persona changing is slicker, his summoning is faster, not having to wait for a card and all, and he's got a gun. The gun would work wonders in the metaverse, but outside, it would still be an effective fake out.
