I've owned the Oura ring since they started shipping v2. Paid something like 350 EUR for it too.
Unfortunately, after many tests and comparing the results with the Dreem 2 (which I also bought around 1 month ago), the Oura ring is highly inaccurate. This has also been tested in studies comparing it to a PSG [1]. The Oura ring is in:
agreement of 65%, 51%, and 61%, in detecting "light sleep" (N1), "deep sleep" (N2 + N3), and REM sleep, respectively.
This means the Oura ring over or under estimates deep sleep by 51% ! That's huge and essentially unusable for anyone wanting to check things based on supplement intake or to track baseline.
I was pretty pissed off (mostly at myself) when I dug deeper into the product and realised how useless it's going to be.
Every morning I woke up and saw all these "awakenings" and how I've slept only X amount of hours and got stressed with my readiness score, only to use the Dreem 2 and see that my sleep is perfect with rare awakenings.
Of course, the Dreem 2 is not perfect, but it's far more accurate than Oura will ever be (as you just cannot assess sleep stages without looking at brain waves).
All that said, can't wait to try this new sleep product! I might wait to first test also the new Bacopa product at 24%.

That's an interesting study. I just read the whole thing, though. It's not as bad as is sounds in the abstract.
These results suggest that ŌURA ring is sensitive enough to capture overall differences in sleep patterns with limitations in detecting wake, as detected by PSG.
So while it does differ in the measures of REM and deep sleep compared to a sleep study, it is consistent in that inaccuracy. So it can detect changed in your sleep quality, and can see differences in age groups. The exact numbers might not be 100% correct, but the relative changes are still useful.
Also, look at the graph between ŌURA and full polysomnography.
It's certainly not perfect, but you are getting a pretty good relative idea of the sleep patterns. This is just a small little ring, after all. I would not expect it to be as accurate as a full PSG. However, I would certainly not call it useless. I would not compare my REM and deep sleep numbers directly to other numbers gathered from a full PSG, but I can compare them to each other day by day. That study also used V1 of their algorithm. I'd love to see the same study ran with the newer one to compare.
I'll pick up a Dreem 2 and do some testing of my own. I am always for gathering better data. I would just be a little hesitant in calling the ŌURA ring useless based off that data. That data actually shows me that even V1 of their algorithm was getting fairly good views of overall sleep patterns. I would assume the newer updates to ŌURA are doing even better. What would concern me is if there was data showing that ŌURA ring data was off on a relative scale day-by-day to its own numbers. That's what would concern me. However, if I can trust the numbers are accurate relative to each other, not necessarily relative to another more accurate measure, then the data is useful. My testing of ŌURA shows that it seem relatively accurate day-to-day. When I get shit sleep, it shows that. When I get good sleep, it shows that. If I just gave you the data from my ŌURA ring, you'd be able to tell the nights I drank alcohol without any problem. You could probably do it without me even giving you any extra info on my patterns. It's that consistent. As long as I am not taking the exact times I was in REM and deep sleep as 100% accurate, that data is still useful. Honestly, can we even expect 100% accurate data from a little ring like this? If it was 100% accurate, why would we ever do full PSG studies anymore? There are always going to be more precise measuring tools. As long as we put the numbers into perspective, and use them for what they are, I don't see any harm in that.
