For frames that have low bases armor values ( such as Banshee with 15 armor / Loki with 65 armor ) it would be best that you focus on Vitality as Steel fiber works on percentages, so you wont get much out of it

(e.g. with maxed out Steel Fiber on Banshee you will only get 31.5 armor (+15.5  from base) which is negligible in terms of damage mitigated ).

While frames with higher base armor ( Frost  with 270 armor / Valkyr with 600 armor ) you can focus on Steel Fiber ( and Vitality if you can afford it )  .

(e.g. with maxed out Steel Fiber on Valkyr you will only get a whopping 1260 armor (+660 from base)

Ideally you'd want to get around 100 armor to get the most efficient damage mitigation ( per armor value ) as you can see from the first graph. But since warframe base armor values are not really that high that you would lose alot of efficiency, higher armor values are always good for your effective health. Hope this helps!
