At the really low levels (like 1st and 2nd) its all about bang for your spell slots. So I prefer rituals at that level. Mage Armor and Shield are your got have "combat spells", everything else is negotiable. I do think sleep is very potent at the early levels so its good to have.
After a few more levels than silvery barbs, a few after that (around 4th and 5th level) absorb elements becomes a lot more useful as elemental types become more of a thing.
