My room is not tragedy Lucky you. Nothing but sadness in woe in mine. For you, yes, I would skip the AT2005USB and go for an XLR setup. You don't, however, have to spring for a Shure SM58. You can get good results with another dynamic microphone like the Behringer Ultravoice XM8500 or BA 85A. https://www.youtube.com/watch?v=6vIY2bEcQOo https://www.amazon.ca/Behringer-BA-85A/dp/B082M96T3S You'll need an audio interface like the M-Audio M-Track Solo and an XLR cable. That's all that's required to get started. Optional accessories include: Shock mount Windscreen Pop Filter If you don't already have a solution you can use a virtual mixer like Voicemeeter to create a noise gate, EQ your mic and so forth. For sound treatment you can improve things greatly with some rudimentary DIYs. A thick rug on the floor, old blankets hung on the walls/windows/doors/overhead cuts down on reverberations. Even a deskpad on your desk or plush furniture cuts down on reflected sound.

To answer your question, yes the Quadcast 2 and 2S are significantly better than the original. Not that you need it strictly for gaming but, the 2/2S are capable of recording audio with higher fidelity. However, being condenser microphones I don't think they're the best choice for an untreated space because they're very sensitive. This is what I'd do instead...

It helps if your son isn't sitting within the pickup pattern of the microphone. I play "other games" after kid is in bed *wink wink* So that gets picked up on my boosted mic as a constant background hum Well. Start with a dynamic mic and don't boost it excessively. In the future upgrade your setup as you get more serious. One that requires less gain (Sennheiser e 835s/845s or sE Electronics V7 as opposed to a Shure SM58 or SM7B) is better. Better mic preamp. Add in a mic activator like a Fethead or Cloudlifter to use less gain. I'm the interim place the noise in the rejection zone of the mic.
