What to bring for my list; Assault Intercessors or Flamestorm Aggressors?

Hi all,

Going to be having my first game in a few weeks at a small tournament with friends, playing a few 500 point games. I’ve got a list at about 410 points and can’t decide what to take for my last 90 points. In terms of options, I can either take a squad of Flamestorm Aggressors, or a squad of Assault Intercessors. Here’s the rest of my list:

** Interrogator Chaplain with the Teeth of Terra and Calibanite Knight trait

Lieutenant in Phobos Armour with Storm of Fire trait

10 Intercessors with Bolt Rifles

Judicar with the Adamantine Mantle **

In terms of Strategy, I feel I could either bring the Assault Intercessors to have a strong melee line to compliment my Interrogator Chaplain and Judicar, or the Flamestorm Gauntlets to get buffed by my Phobos Lieutenant and have some great overwatches. I don’t know the exact lists that will be present, but the enemy armies are Black Templars, Orks, AdMech, Necrons, and Guard.

Thanks everyone, I appreciate the input and am excited to hear everybody’s thoughts!
