| Support quality | No support evidence found | No usable evidence in sources reviewed |
| Public sentiment | Long-time users praise audio quality and low latency but consistently warn the setup and interface are not beginner-friendly.² | Users consistently praise voice quality and low latency but cite setup friction, missing features, and an aging client versus Discord. |
