For profit is fine, although their APCs are much higher for OA. The trouble is that even if you do pay the APC, journals routinely screw around by delaying or "erroring" the open version to try and extort suckers. (And they wonder why we now submit our proofs directly to sci-hub...) You pays your money and... (Ask me how I know this)
It doesn't take that long to count citations, which defuses the usual excuse for using impact factor as a metric. (And some really shitty journals have surprisingly high impact factors -- they just don't publish much of anything in a given year, e.g. Science Immunology has exactly one primary research article in its entire August 2018 issue!)
Ultimately, it's funders who decide what "counts", because indirects from grants (money money money) is the only real currency. You can publish once every five years in the Journal of Irreproducible Results, but if you have a $20M P01 for those five years, you're getting promoted anyways. So when Chan-Zuckerberg or the Gates foundation says "OA or nothing", then it matters. Universities will keep licking their balls until the purse strings tighten, but once that happens, hoo-eee! It's amazing how quick them OA pubs count for promotion. (Secret: it was never the publications.)
