Is there any difference between these Rubik's Cubes?

[The Subject]

So I've been looking to buy a speed cube because I used a friend's today and it was very nice to use. Afterwards, I decided I would buy my own.

Here's the catch. There's three different companies that produce this cube, as far as I've researched, that are available to Amazon Prime.

There's the Dayan Zhanchi, Newisland, and Cyclone Boys.
The price goes down with each link, but I don't know if that's a sign of quality or not.
Does anyone here know anything about the differences between these cubes?

First link has 2.3 inch sides, is 2.4 ounces (Explains the largest price)
Second link has 2.2 inch sides, is 0.3 ounces
Third link has 2.2 inch sides, is 0.8 ounces

Only thing I can think of is just different manufacturing costs. However, I don't know anything about these cubes, I just pulled that data from the store pages. It might be the reason why though.

Also some people prefer really light cubes, others prefer ones with a bit of weight to them. Supply & demand is also a factor.

Went ahead and bought the Dayan Zhanchi. Thanks.
