It's highly illogical that someone of Super Saiyan Gohan's level could be beaten by someone like Android 18, or have difficulty one-shotting her physically.
Again, your argument is extremely arbitrary. Can you prove that two small SS Gohans in a restricting suit could defeat #18? If not then you don't have a case here.

They are not implied to be a league above her
They are. The fact that Trunks while not even at full power makes her scared for her own life speaks volumes about how they relate to her.

and it's common sense that dictates how over-rated they actually are
What "common sense" is to you isn't necessarily common sense to someone else.

-aside from a few sparring sessions that can be explained for essentially what they are; sparring sessions
How is that an argument exactly? By the same twisted logic I could just as easily say that Goten is much stronger than Gohan and if they weren't sparring then Goten would one-shot Gohan. Not that it'd hold any merit; I'm just showing you how your argument is incorrect.
Also, we've seen sparring matches before where the much stronger person blocks the other person's attacks with ease. If Gohan is much stronger than Goten then shouldn't he be able to block Goten's blows with ease? And shouldn't Vegeta be able to easily dodge Trunks if he is much stronger? Or are these two situations the only exception because it's convenient for you?
Poor argument.

they are never implied or shown to be anywhere close where you or anyone else thinks for that matter.
Not in any other statement, fight scene or material that comes afterwards.
Except for the mentioned feats of giving Gohan a hard time, landing a hit on Vegeta, and nearly one-shotting #18 while not even at full power.

They're not overrated at all. They're underrated because people can't seem to accept the sentiment of strong children when that's clearly a recurring theme in Dragon Ball. No amount of excuses can change the fact that they're on par with Gohan and not leagues below the adults.
