Yeah it will be a challenge to compete. In particular in gaming latency in voice defeats the purpose of having voice Comms in the first place. You also need push-to-talk, voice activation for people with good mics, noise cancellation and - ideally - the ability to set the region for the voice server. EU gamers on discord are unlikely to set a US voice server for Comms and vice versa. For my community we've decided to go with a nip-29 relay for chat, images, videos etc and until good voice solutions evolve around nostr we'll probably setup a TeamSpeak or Ventrilio Server. But will definitely test Flotilla as well.
