I actually don’t know how long the outland process currently is on average. I think I read someone in these forums from Denmark who got it after 8 months, but I haven’t come actoss any specifically from Denmark since that, so it’s hard to tell just from one case. But I’m also not following the outland threads as much, since I am an inland applicant myself
I feel like the inland route is definitely the best option if you’re interested in the OWP. I believe the OWP is actually quite difficult to get otherwise - in fact, I don’t think you can get a OWP at all if you go the outland route.
