HereSphere has a visual quality far superior to other applications and plays seamlessly on Quest 3 without any lag. But the biggest advantage for me is the controls; holding down the Grip button to rotate the screen and adjust the angle is very convenient and comfortable. Additionally, zooming in and out without distorting the image using the analog stick is very easy, making it very easy to correct models that appear excessively large or scenes that are too close or too far away in some scenes. Also, it's very nice that it automatically saves these adjustments made.
I've just purchased an annual membership for SLR. However, due to my difficulty in getting used to the controls, especially in the DeoVR application, I will continue to use the HereSphere application. Therefore, I will have to download and play the contents compulsorily. Hopefully, someday we can also stream from the HereSphere application.
