Go with elvaan because not only you look cooler, but you also have more HP. The extra strength don't really do that much. Base stats don't really do that much so race consideration isn't as big of consideration as equipments.
It's wrong to not take into account of equipments. There are a lot of great items that are rare/ex that most ppl don't even know about. And even if you do, it's very difficult to get them since some are 1 real day spawns + rare = > 1 week camping = insanity, at least for me. It's not practical so say, o, I will have hawkers + 1 at lvl 30 (worth millions or lvl 80 crafting + very expensive materials and gl on not failing and making the +1 version) and shooting patricarchs off loxley at lvl 57 because that won't happen, even at end game. Not even jpn players have all the best stuff and they are still running arount at lvl 75 lfg.
Elvaan are slightly better because of rng equipments and traits that are often gear toward accuracy. Statiscally, if you have 100 points to distribute between damage and accuracy, the correct answer is an even distribution of 50/50. You can prove to yourself that is true with some calculas or statistics. In the game however, you get tp only if you hit so you would want a lean on acc, but you get that easily with traits, natural rng stat agi growth, and equipments so you really want damage really. That said, I think elvaan is a better choices on top of extra style points and HP. But again, the difference is so small anyway that you can just flip a coin.
