On the plus side, we now have a choice. The slight negative is that if you plan to deploy on the web, as opposed to Babylon Native, you probably need to test both.
If you are not going to deploy at all, like a back office tool scene, you can pick the one you want. I was disappointed that the Oculus browser did not have speech recognition. I would like to have text input fields without a keyboard. I can use this for my Studio Suite tool, if that is the case, to give poses a name as an example.
