I'd say it's a bit better. I've been using DroidCam as a third camera in my remote guitar lesson OBS setup, and it's been OK, and I think this would be much the same (using an old phone - MotoG5 - as webcams are like gold dust at the moment).
An upside of this is that it doesn't need another piece of software running on the Windows machine - the driver effectively does it, unlike DroidCam which needs the program running on the PC to work.
Also, you can change the resolution directly in OBS, and I've just set it up at 1920*1080 which seems to work fine, and gives a better quality image.
Lag seems similar on both, but I've not tested it other than visually - no measurement made...
