Uchigatana, or Iaito.
When it comes to those two, the choice really depends on your preferences.
However, in case of Broadsword VS Longsword, one has more to consider than just damage, reach and moveset. That is chaining. Both of these fine weapons have very deadly combos you can utilize to take away even a whole HP bar of your opponent.
I've been using each of these for many hours, days even and can't decide.
Broadsword has a handy 1H combo, which can catch people off guard, but it's usable mostly against low to no Poise opponents and those usually know how to Toggle Escape. Further, it's roll R1 has a horizontal slash. While short in reach, it can be used to further combo with ease when it hits. However, the weapons shorther reach gets me backstabed often as I have to get very close to the enemy. Finally, it has slightly higher damage, which I believe is too tiny to consider for PvP purposes.
Longsword lacks a decent R1 combo, but it has a pretty useful poke instead, which is nice to punish rolls and keep people off you. It's 2H roll R1 is also good to catch people that end their rolls and can be used to combo as well, but landing a hit with it is much more difficult. On the other hand, it's longer reach makes the weapon a bit safer as It doesn't get me backstabed as much.
Finally, I prefer how Longsword looks, but I don't want Fashion Souls to be the decisive factor here.
I'd like to pick one of them to get fully used to it, instead of switching between them.
Help me choose, please.
