On paper, the thrusty swords look awesome: 31p, 150 range on a 100 speed weapon that you can use with a shield ( +3 long espada).
In practice, they glance at any range <90ish (which also stuns you), and the stun after being blocked gets you killed A LOT. The unpredictable 1h thrust hitbox means you will whiff on what looks like obvious hits, and TK teammates WAY off to your right all the time.
All that said, when you actually pull off a spinthrust into someone's face to one-shot them, it is one of the most satisfying experiences in this game. I do better when I pick up a +3 elite scimitar, italian sword, NCS or KAS, but I have more fun with my +3 long espada.
