Is a Quad Cortex/Mini Cortex right for someone who doesn’t gig?

Pardon my ignorance, as I’m sure this is a question that could be argued either way endlessly. I am just a bedroom guitarist and getting into recording my own music again after not doing it since I was in a band in high school (over a decade ago now).

My main question is: I have the Gojira and Nameless plugins at the moment, and I’m wondering if I’m better off continuing to buy the plug ins I desire, or buy the QC and have access to much more. Obviously it is much more cost effective to buy a couple plug ins,, but the idea of possibly being able to play live if I wanted to do that again is nice, or if I decided to get a small cab to play instead of headphones or monitors.

Not related: but if anyone is willing to listen to some real rough demos and give me tone feedback, I would appreciate it!
