Need help deciding

[stinkydavis]

So I am trying to decide how to aqua scape my new tank. I got about 100lbs of what I assume is Fiji rock because it is super heavy for small rocks. Making it not very possible to aquascape and more of a stacking rock.
my main questions is is worth purchasing something like Marcos rock or caribsea dry rock. Or is it not that much easier to work with?
Here is the rock that came with the tank.

No rock is easy to work with or glue together it’s a pain in the butt and doesn’t hold very well but the water helps hold it. I’d say use that rock instead of spending more money!

Take a hammer to it so the piece aren't so bulky.
