Honesty you
might be better of getting the Steelseries one and pay the extra
I had the really old Goliathus and ,apart from the edges fraying, the quality of material was perfect. However, they're now changed it.
It used to be a much heavier, textured, almost industrial type material with a really controlled glide. They're since changed the material to a very light material with a much less unique texture. I'm not entirely sure how to describe it, i can only give my opinion that i personally dislike it
I feel as if they've kinda cheaped out this time, althought they fixed the fraying edges they're using a completely different material.
Go for the steelseries if you don't mind paying the extra. I think the extra is worth it, thought. That being said, that price is extremely cheap for a Goliathus and isn't so bad.
errr, hope this helps
