In the last WebAIM Screen Reader survey [0], if anyone answered they primarily use Orca, they got lumped into "Other"; out of over 1,000 respondents, 7 primarily use Chromevox so the Orca number must be lower than that. If some use Orca sometimes, they must have been less than 1% of the respondents and got lumped into Other for that question as well. That doesn't mean that Orca doesn't do a good job or that it works very differently than other screen readers. The A11ySupport site [1] does have some data on Orca's support for specific code. For instance, it fully supports the aria-expanded attribute but has no support for description list elements. If you have an iOS or Android device, using their built-in screen readers might be more instructive.
