I am going to disagree to an extent.
It takes an excellent writer to handle high powered characters, particularly those with non-physical components; being good is not good enough.
Why? Because once you get past a certain level, it is very hard to ground the fight so readers understand the power levels of characters and why they are a threat to the protagonist. You can instinctively understand when you toss a mountain at someone; the person is STRONG. But energy blasts? It becomes abstract and very arbitrary at a certain point. You can tell a reader what's going on, but it's very hard to show.
