Hm. I'll probably try emulating it, yeah.
Emulation isn't efficient, it's just a way to see something how it works.
My main question is: Is Amiga just a more efficient/effective OS than Windows or Linux? Will it use my somewhat limited RAM supply to greater effect?
Here is an interesting reading, although a bit old.
Your "somewhat limited RAM supply" must be more than the usual stock Amigas (varying from 256KB to 18MB on board -the so called "classic line"- ) with an OS that provides graphic interface and console.
Check out the
Amiga Wiki.
What are Amiga's advantage and disadvantages? 
In your case, as "a hardcore gamer", there are only disadvantages (except if you're interested in some
old games). I you were a developer, you could find interesting both AOS & Aros (speaking of Operating Systems, and not just the applications)
