[Whats stats should I use on a Caladbolg Orchida Greatsword?]

Thanks for the opinions folks. :)

[Whats stats should I use on a Caladbolg Orchida Greatsword?]

I currently have a Ranger.  I play PVE as a Druid, but I recently unlocked SoulBeast.

I'm tempted to make by Caladbolg ascended sword into either Maurader, or Celestial.  I understand that Berserker is often meta, but I seem to die too frequently when I equip Berserker gear.

Another class I am interested in playing is Guardian.  Would Celestial or Maurader be a bad choice for a Guardian?  

Basically, I was hoping a veteran could offer me some suggestions.  I'm hoping to start using the weapon soon, but I'm not sure how to stat it.
