Actually, higher level beings can withstand the spear. I'm thinking here about when Cao Cao stabbed Ophis and it had zero effect. Also when Cao Cao attacked 1st gen Sun Wukong, he blocked the spear with his finger.

So yeah, the spear is the most powerful longinus, but it also depends on the ability of the user.
