ILLEGEAR is considered "Not Expensive". If you own one then you'll understand.
A GTX and IPS screen, at that base price is already a good deal.

You may say, illegear base specs won't have say, ssd's or even OS or Enough HDD space or RAM comparatively for it's price vs other brands, but that's what that makes it even better.
You will know exactly what you've paid for. ( i doubt the quality of other brands because they give good specs for lower price even if it's mass produced )

Think twice before reconsidering, knowing what's in your machine and EASY maintenance and Adaptability ( you can buy and add your own ssd, ram, hdd ) without voiding warranty as said by Prince J.
I asked this before i bought my RE-15.

That saying, budget matters so it's clear, go for Lenovo/MSI.
I'd say MSI>lenovo.
