Ging is stronger than Chrollo individually speaking, but that's not worth much, his aura definitely isn't anywhere near the Royal Guards given absolutely no one freaked out when he used his nen in the Pariston chase scene, sure you can say "he held back" but that's besides the point, even when holding back the RGs could freak out extremely experienced hunters with their sheer amount of aura, Ging isn't made of the same mold as them.
And Chrollo has the perfect hatsu to beat people stronger than him as he can adapt to many different situations.
But we know jackshit about Ging's actual ability so it's literally a guesswork when it comes to who would win with prep and especially how good is prep when you know absolutely nothing what your opponent can do?
What are Ging and Chrollo gonna prep for? We don't even know what "prep" means in Ging's case, with Chrollo I guess he could always come up with something that should theoritically fuck up anyone regardless of their abilities but he'd have to be very creative and think of every possible nen application Ging could have for that.
