Which is better for me, Rust or Hurtworld?

[Miyamoto Musashi]

I'm thinking about buying either of the two but I don't know which one is better for me.
I've heard that Hurtworld is better for those who don't have a great PC as Rust is more demanding. I think I might be one of those people as my PC is not that good.

System properties:
Windows edition: Windows 7 ultimate edition
Processor: Intel Core i3-3217U CPU @ 1.80 GHz
RAM: 4 GB
System type: 64-bit operating system
GPU: Intel HD graphics 4000

Considering this, which one should I get? Also tell that which one is generally better and more fun.

Honestly, you shouldn't buy either until you get better specs, buy a game that doesn't require great specs, I have a 3,1ghz dual core processor with 8 gigs of ram and I get lag on fastest on rust.
