Grand Inquisitor vs Darth Vader (read OP)

This is the official rematch between the apprentice and the master. You can track the Grand Inquisitors growth by his fights with Kanan who seems to grow at a miraculous rate if you so desire. This is an open for interpretation thread who wins?

This is Darth Vader at the beginning of the Charles Soule Darth Vader series specifically as of Issue 6 when he faced off against the Pa'un for the first time.

This is the Grand Inquisitor as he appeared in Star Wars: Rebels Season 1 Season Finale, and any knowledge he would have of Vader and his fighting style as well as other prior knowledge applies. 

Can the student finally surpass the master?

Vader probably wins because his hatred is just boundless.

Vader slaps

i mean, kinda self explanatory.

GI < ventress ~ TCW kenobi < mustafar/ROTS kenobi <= kirak << vader

vader destroys

The GI is with Ventress not beneath her and Vader is equal to Infalla.

I don't think this is a stomp because the GI has 14 years to grow more powerful and is very busy training the other inquisitors daily. Literally all they do is train and hunt Jedi. 

I think it's very possible that the GIs knowledge of Vaders style combined with his potential growth renders this a decent match. Though this is all speculative

Vader still wins.

Vader overwhelms him.

Vader wins by merit of raw power. However, the Grand Inquisitor's skill would make it a tough duel, until Vader decides to just ragdoll with the Force.
