Thanks,
Remember that On1 is work in progress. I once took part in the same thing when LR was developed. It was also a bumpy way forward. It took to version 3 or 4 before it was really a stable and matured software.
ON1 have many aspects that speaks for it. Longterm I think it will be a great software. However it still have a number of bugs and issues.
Compairing different raw-converters is difficult. Different softwares can be good at different types of pictures.
Some might render the colours very well and others might be able to render the details.
I did a small test with Acros SOOC and some alternatives converting Acros from the raw-file. Not a great photo, but a good one for testing.

Acros SOOC X-PRO2
Many talk about how great Acros SOOC is. Well, I tried it for a couple of days. I am not so impressed. The SOOC has the worm artefacts if you zoom in a lot. They should not be there. Try to sharpen the image a bit more in post or add clarity and you start to see these artefacts quite clearly also in small images. It starts to look artificiell.

Raw-file converted in LR with Acros preset.
If you use the LR Acros preset you of course have more control. You can fine tune a bit more. However the LR also has the problem with worms if you zoom in enough. If you try to sharpen the image or use clarity these artefacts starts to show up.

Iridient Conversion
Iridient has been my tool for years when I was not satisfied with the LR result. It is still one of the best.
This is On1 from the latest version. I think it is one of the best.
It gives a very sharp and a high resolution both in the grass, the gravel and in the bushes.
Again I want to say that these tests are very subjective. You have to manipulate each software without being able to compare the result from another while you editing. It is easy to go overboard in one of them. So try it out yourself and see what you like.
For 80% of my raw-conversion I use LR and even if the result is not top notch I think it is good enough.
