Gaming Mouse: Dragon War or Logitech?

So, last time i bought a gaming mouse, was 1.5 year ago.since i had a small budget then, i settled for a lenovo gaming mouse. It was pretty average, with 2 extra buttons, but now it's beginning to die, so i'm going to buy a new one.
I want to buy one which has good sensitivity, and a longer life. Currently within my budget, i can go for either Dragon War mice, or a Logitech g300, so can someone help me pick? I'm looking at at 4 Dragon War mice: Thor, Unicorn, Chaos and Leviathan. The most popular seems to be Thor.
Now, it is a fact that the g300 is almost double the price, so i'm really considering Thor, but i'd like to know if Dragon War mice last as long as the g300, or die early.
Also, i'd like to know if one of the other 3 dragon war ones are better, because they're more or less the same price.

So… Dragon War ELE G9 Thor OR Logitech G300?

My last Logitech G5 lasted 8 years, and still works. I just fancied an upgrade. I've never used either of the mice your looking at, but I down to previous experience I would go for the Logitech.

Yes

G300 or even better, the Logitech G502
