As a Gunlance main, I'd want to recommend that... but while it does have a nice easy guard (and can be built very tanky), and blowing things up with Wyvern's Fire is always fun, it is sadly the complete opposite of fast.
But seeing as you're already used to switchax, and playing World, I'd recommend charge blade. Sword and Shield is faster, but also has a weaker shield (at least, compared to when charge blade's shield is charged up).
