Terra Blade for sentimental value, Last Prism for damage over all.

Phoenix Blaster all the way.

It's not particularly good, but it is particularly cool.

Scourge of the Corruptor and Death Sickle. They're both really cool and fun to use.
@Kazzymodus it is actually pretty good, it's damage is comparable to the megashark and it can take you to about plantera if you're determined, and it's available pre-hardmode.
