^^ Right. In this case, you are using the exact same element, so it shouldn't entirely be able to overpower the other for just that reason. Now, in the case of the Magu Magu no Mi and the Mera Mera no Mi, the element of Magma is superior to the element of Fire, which is why it's able to overpower the other.

A thing to keep in mind here is that a Logia cannot grow any more powerful than it already is, unlike a Paramecia or Zoan. That being said, its power always remains the same, which is why Logia users are feared in the Grand Line, because sailors are hardly known to use Haki there. However, that's not to say Logia are "bad"; they're stated to be the most powerful for a reason.
