While I appreciate that you decided on Nim, I will repeat what others said: Don't think in terms of "no GC vs GC", it's useless, especially for Nim which offers kind of a continuum.
"Oh, low level, I cannot use a GC here!" \- "Maybe, maybe not. I bet you can and you're simply repeating bullshit you read online." Btw when you program "low level" you might not be able to use floating point arithmetic yet somehow this topic never comes up...
