The Pentel Smash mechanical pencil is usually compared to the Pentel Graphgear 1000, but I’d like to ask you comparing Smash to Graphgear 500.

Where I live, both are expensive mechanical pencils, but Smash is 70% more expensive and, IIUC, more professional. I’d like to know whether it pays to choose Smash over Graphgear 500 or both are kind of similar so I should go to Graphgear 500.

Do you know them? How do you compare both?

Thanks!
