Would you pay to watch Errol Spence vs. GGG spar? And who you got??

I mean both of these guys have the reputation of being the best sparrers ever. One guy gave Mayweather a black eye, and the other makes cruiserweights quit!!! IDK about you all but I would pay to see this because I love boxing so much I pay for it.

So with that said in a 3 rd sparring session with 16oz gloves, who wins? Who would be A-side?
