In my multi-stage exploration of the data on ACA private plan buyers' metal level selections, I have been pleasantly surprised to determine with a fair degree of confidence that about 90% of shoppers on healthcare.gov with incomes under 200% of the Federal Poverty Level selected silver plans -- and so availed themselves of the Cost Sharing Reduction (CSR) subsidies available only with silver. For all ACA buyers on all exchanges, the figure is a few percentage points lower, since many state exchanges did a much poorer job than healthcare.gov in steering CSR-eligible buyers toward silver.
While CSR is available to buyers with incomes up to 250% FPL, the rate of silver plan selection (necessary to access CSR) falls off a cliff at 201% FPL. That's wholly rational, as CSR weakens as you move up the income scale. For those with incomes between 200 and 250% FPL, CSR bumps up the actuarial value of a silver plan -- that is, the percentage of the average plan holder's yearly medical costs paid by the insurer -- just three points, from 70% to 73%. At lower income levels CSR is much more valuable, raising AV to 87% (for incomes at 150-200% FPL) or 94% (for incomes under 150% FPL). Accordingly, in New York (one of the few states that breaks out metal level selection by income level), 89% of buyers with incomes under 200% FPL bought silver -- but just 59% of those between 200 and 250% FPL did.
With all this in mind, I was surprised to read* in the latest CBO updated ACA cost projections that the Department of Health and Human Services and the Joint Committee on Taxation have been surprised that more buyers eligible for CSR have not selected silver plans:

Outlays for cost-sharing subsidies over the 2015–2024 period are currently projected to be $39 billion less than previously estimated, primarily because CBO and JCT now expect that more people will forgo those subsidies by choosing to enroll in a bronze plan instead of a silver plan...
