Any suggestions?

That's easy! Blue.. no Apprentice or Atronach.

I use the Atronach stone on my Nightblade, since recovery is nice to have, but if you want to be more burst heavy you should go with Apprentice.

Depends on your main main DPS Skill, IMO;
Funnel Health- Apprentice you've got enough sustain to last indefinitely so more spell damage from not only you mundus stone but everywhere else needs to go into spell damage
Concealed Weapon -Mage CW hits hard but costs about 50% more than Funnel Health to sustain so you need the extra Magicka to help with some sustain while providing damage
I'm a healer NB not a DPS; probably atronach to help your sustain after spamming big area heals.

I'd take this list with a gain of salt, I use Funnel Health and love the Apprentice.

Use apprentice, i only need more recovery when aoe grinding and use siphoning strikes and a mana pot if i run out.
