I'm just curious since I got the Troika a few days ago. It requires a different mindset than a Calibur, I noticed. Calibur knights often tend to charge in and slap [scrap] up left and right because its faster attack speed opens room for that, but with the Troika and its 2-hit combo, that's most of the time not a good stratergy.
If I wasn't clear, I meant switching from a gunslinger to a swordsman or something similar. In my case, switching from Calibur to Troika.
Love the ridiculous damage it has, though.
Using both swords can be awesome after getting weapon slot upgrades and trinket slot upgrades, just to fill yer fun out, but since ye might be new, starting out with any of those swords ye like are nice.
It depends on yer playing style, ye know. Troika can knock back and reset's enemies motive(action) after the second hit, so does the Calibur on third hit. I strongly recommend using Calibur as it's charge attack can knock back further, while Troika's charge attack takes too much time. Note that using Calibur can be sabotage sometimes, as the knockback might cause some enemies not to reset their actions and probably bump to party members and hit them. (also goes with shield bumping)
Every weapon has it's pros and cons. Likewise, it depends on yer playing style. ^q^
