I have (some) experience with various idaas providers from a stint in consulting. I'd say I t depends on what you want as an organization.
The Okta apis are decent but (when I used them a few years ago) a second rate citizen from a development standpoint. At least back then they'd advertise functionality but have very limited api support for them.
As a developer I highly prefer Auth0 over any other options (though Okta would probably be my second choice) but especially at enterprise level negotiations it costs significantly more.
Edit: Mind you, I'm not an expert on these. I've just done (or prepared) implementations with some of these products in an enterprise-y setting.
