Hey there,
There are quite a few pixel streaming platforms out there these days: https://www.streampixel.io/ is actually one of the better ones, in my experience. What really separates these platforms in terms of quality is their hosting setup and GPU infrastructure. As far as I know, Streampixel uses top-tier GPUs, which translates to noticeably better performance for demanding projects. You might want to give them a try and compare the experience to some of the less optimized options.
At the end of the day, since all these solutions (including GFN) are built on WebRTC, the real differentiators are smart network optimizations and solid graphics hardware.
Just my two cents!
