Survivor Vader was a little bitch compared to fallen order Vader imo. Spoiler alert for survivor, I get that Cere is strong, but I don't think she would've ever done THAT MUCH damage to Vader. Vader in fallen order was absolutely terrifying and untouchable. The way he hobbles away in survivor is comical. Unpopular opinion but they really wasted him, AND he's not that tough of a fight at all since they made it that everyone faces him at the same difficulty.

So idk, guess my answer is always going to be rogue one
