Melee Champions: Electropriest VS Sicarians

Hi there followers of the Omnissiah!
I have an internal debate I want to share with yo:. Electropriest or Sicarians as best Melee unit.
I love CQC and I think AdMech is really good for it as you also receive a lot of support from other shooty units while you shred your foes to pieces or BBQ them. I have been looking at both Sicarians and Fulgurite Electropriest rules and I don’t know who’s better as a melee unit. Honestly, Sicarian ruststalkers look kinda more balanced than Fulgurites but the Priests have some really heavy rules for MW’s and hit really hard. I would use them deepstriking them inside my trusty Termite drill most certainly, but what do you guys think? Who’s for the win?
Thanks in advance Servitor of the machine God!
