This is real simple to figure out even if speculating. How?

They both negate each other. GER and TWOH abilities can't win against one another because it will be in a constant loop of cancelling each other out. You can say GER abilities range is universal but TWOH abilities can rewrite at the same time since it's literally limit to the stand hands. Here's an examples :

GER nullifies TWOH overwrites from a distances; TWOH rewrites the nullification at the same time, thus nullifying the nullification. Things repeat, thus it's a never-ending cycle of cancelling each other out. It doesn't matter if one was faster it will still cancel.

Now that's the abilities out of the way. Lets look a the Stands destructive power and speed.

Easily TWOH is more powerful and faster than GER since it went toe-to-toe with Star Platinum and also overpowered it in a stand rush. I know some will say GER will just null the damage like it never happened and GER is actually more destructive since it fling a pebble so fast it pierced a hand and smash a column.

First of GER null abilities is either inconsistent or not explore on much since Araki didn't expand more of GER in part 5 and just left us with the GER we know now. Second if GER destructive power has increased then it needs to show more than just fling a high-speed pebble and smash column with said pebble. Remember when Star Platinum punches diamond teeth? TWOH is basically the same just a little more stronger. Coupled those with vampiric abilities(or whatever HA DIO is) TWOH beats GER in a fight. Their abilities would just trump one another infinitely but you can't rule out destructive power.

So yeah TWOH can beat GER in punching each other but their abilties will never have an advantages against the other since it's impossible. But this is still speculation though since THOW isn't canon and GER isn't expanded on so we'll never know it's limits and/or drawbacks
