(sorry it took me so long, just got my computer back)...
yes, i am, since thats what his style is supposed to be about- he made it to be uncounterable to other styles, hence why obi wan had to make a new one, and why he had trouble with his own style.
i meant best style as in, out of all the styles ever, his own unique one is literally the best one aside from vaapad, which is mostly good because of hax. vader's style is a force user's killing style. it doenst have the hax that vaapad has, but it does have the best of all other styles added into it, which vaapad does not.
no, vader was trying to beat him, and only said he would consider killing him, if luke tried to do the same, which he kinda did when he got mad, which was literally the only time he gained the upper hand on vader (he had to get a huge ass amp to even best vader who was holding back, not using the force, and conflicted aka not using the dark side- thats what luke was equal to). both werent trying to kill the other, but luke blatantly tried to do so when he got mad. he just stopped cuz, well, he came back to his senses.
other numerus soruces say that vader was never going to kill him, that he was holding back, that he was the second strongest in the galaxy (which means above luke skywalker, and above the people that luke later fought, aside from those in the legacy era). i can show u them, btw. and believe me, they are plenty, just as u said. this is probably the most contradicting thing i have ever seen. i would have taken luke's side tbh, just like u, if it werent for the fact that by feats themselves, vader never had to use the force and that vader was said to be a palpatine killer lvl being by sheev himself in the jedi vs sith guide, while luke was merelly a growing threat by that point.
i know its not. but the place she was at was still a light side nexus. bro, rooms can nexuses if need be. things can also be nexuses. she forced the light side on the planet itself, making her spot a ligth side nexus, which weakened him, and made her stronger.
i dont need to convince anybody. she was more skilled than any of the people u mentioend above (in both force and sabers), one of the best in the order by statements, and even then, what good feats do either of them have when not amped themsevles? and btw, u kinda just reminded me of something- amped shak ti< galen< pissed off galen< starkiller< pissed off starkiller< prime vader, while revan was barely above amped malak, who he himself had no good feats previously.
i go by the game primarely, so idk much about the novels; and even then galen was amped by his rage when he fought vader as an equal, since before that he was being ragdolled to an extent. after that, he was said to be in a state of oneness- not even sidious could overpower him, and that sidious is stornger than the sidious that fought yoda, who is still the storngest light side being to ever live at the time, including light side revan at his prime (stornger than the revan being used here). then, galen's clone gets even stronger than that, fights vader again, and if im not mistaken, galen not only uses help from those rods to power his attacks to fight vader, but also one of the novels themsevles even say that vader is too strong for u, galen marek, to fight him (could be an in-game thing tho). last but not least, the game creaters for tfu 2 said that in the 3rd game, which never came out, u learn that vader was holding back, and testing thep player/starkiller the whole time.
