Easy to clean harder to scratch
Forgot to add WILL eventually leak. Glass/Acrylic is a matter of personal preference and hardly worth arguing over. While glass is harder to scratch it still CAN be scratched. Once glass is scratched the scratch is permanent. Acrylic scratches can be buffed and there is no glass that is as clear as acrylic(not even "starfire"). They even sell kits to repair the scratches without draining the tank.
Also the only thing keeping the water in the tank with a glass tank is a thin bead of silicone. While this bead rarely fails catostrophicaly it can fail. I was stitting in a living room as a teenager when my friends 200g arrowana tank ruptured at the seem. 200g on the floor in an instant is no fun. That tank was only a few moths old and purchased brand new.
After experiencing that I have always prefered acrylic. If you pick it up used it is generally no more expensive than glass and can be buffed back to perfection with a little effort.
So with all of the benefits of acrylic it seems like a moot point that glass is "harder" but not impossible to scratch. There is a reason that anytime you see a large (500g+) tank in a department store or restaraunt, casino, or public aquarium they are all acrylic. That reason is not that glass is better.
That being said, the OP is selling a brand new tank for a fantastic price and I am sure it will perform well for whoever purchases it for quite some time. GLWS
