Every 300 armor raises your Effective Health by +100% of your Warframe's Nominal Health. By equipping max-rank Vigor (assuming Vitality isn't equipped), you'll increase your Effective Health by +120% of your Warframe's Base Health, which is your Nominal Health minus the health gained from leveling to Rank 30.

So if you've got Saryn in mind, you've got: * Nominal Health = 375 * Base Health = 125 * Base Armor = 175

Since the base armor is 175, Saryn's base effective health is:



If you add in max-rank Steel Fiber, you get 367.5 armor—an increase of +192.5 armor, which is +~64% of the 375 nominal health, or ~+240 effective health.

If, instead, you add in max-rank Vigor, you gain +120% of the 125 base health, or +150 nominal health. At a base armor of 175, this is an addition of +237.5 effective health, which is amusingly a whole 2.5 effective health points less.

But honestly, you're right. Most Warframes have less armor than Saryn does, which stunts the contributions of Steel Fiber, whereas plenty of lower-armor Warframes still have the same or more health. That being said, don't underestimate Steel Fiber on the high-armor frames, and definitely consider using both types of mods together.
