What are the best tradable 2H Melee swinging melee weapons?

Excluding all Auto-melee weapons.

I'm running a 2H Melee build. Currently using Pitchfork, Whacker Smacker, and Scythe.

Things are getting a bit dull at this point. When I was at lower level, having to frequently change to higher leveled weapons kept things interesting. I'm currently at a point where I can't get Warglaive plan and not even close to approaching questline that give V63 TwoHander (don't know the spelling the German word, sorry for that).

I'll probably look for something I can buy with 5-10K caps and compatible with Full health build.

Bonus question: Is Oathbreaker (cryo) a good weapon? How does it compare to Scythe or Whacker Smacker?
