@brianportugal I’m among those who hasn’t been able to notice a meaningful difference when even partially controlling for different streamers in my home.
I’ve stuck with my comparatively inexpensive DIY since I like the freeware interface well enough and failed to notice predictable differences between it and much “better” models. Like a previous post stated: support and software should be your primary concerns. Streamers are limited-purpose computers.
The rest of our respective systems are fairly different, though, so YMMV, who knows. No one for sure yet. 😉
