My god...
...I didn't think it was possible to be that stupid.
Here, I'll take you through the meanings, why you are wrong, and I'll use the dictionary to help (as you don't seem to understand, and like to argue with facts).

Coming to think about it, this quote really doesn't mean anything; a warrior in his prime - the best he has ever been (not ever will be),
The best he ever will be is his prime. Do you know this?
prime ( P ) Pronunciation Key (prm)
First in excellence, quality, or value. See Usage Note at perfect.
First in degree or rank; chief. See Synonyms at chief.
First or early in time, order, or sequence; original.
Of the highest U.S. government grade of meat.
Mathematics. Of, relating to, or being a prime number.
Prime means highest in quality, and/or excellence. Which means that at no other time will Maul become greater than he will be in TPM.
The earliest hours of the day; dawn.
The first season of the year; spring.
The age of ideal physical perfection and intellectual vigor.
Third line especially, and here we turn to the quick definition, also known as the thesaurus:
Main Entry: prime
Part of Speech: noun 1
Definition: best
Yes, care to argue with the dictionary? "A warrior in his prime" translates to "Maul during his best point".
QED.
never to be any better - he would never get any better (because he would soon die),
It wasn't written so as you knew what happened later, it was telling you in the now; not with future reference, but in the now. Point moot. It says he would "never be any better", ergo he won't be. Adding to the points above, and this collapses as well. Your argument is falling apart.
his powers at their apex - his powers at the highest point that they have ever been (not ever will be).
"At their apex"
Again, I'll turn to the dictionary for dictiopwange:
a·pex ( P ) Pronunciation Key (pks)
n. pl. a·pex·es or a·pi·ces (p-sz, p-)
The highest point; the vertex: the apex of a triangle; the apex of a hill.
The point of culmination. See Synonyms at summit.
Sadly, since apex means the highest point (the being keyword), no other point in Maul's life could ever surpass that. Oh, and if you'll notice it says "the point of culmination", and I bolded "culmination". Why? It furthers proves my point, and you wrong:
cul·mi·nate ( P ) Pronunciation Key (klm-nt)
v. intr. cul·mi·nat·ed, cul·mi·nat·ing, cul·mi·nates
To reach the highest point or degree; climax: habitual antagonism that culminated in open hostility.
To come to completion; end: Years of waiting culminated in a tearful reunion.
So, you see. Combining this with the previous two points - you're wrong, and you cannot argue with the dictionary, adding to the fact that all these points perfectly add up to mean that TPM was Maul's summit of power.
This really doesn't actually say that he reached full potential.
Actually not. You just completely showed us how stupid you sound, and considering the dictionary itself just handed you your ass - you're wrong, but you're always welcome to argue with facts, canon material, and try to make stuff up, and lie. Horrible tactics when you have a dictionary, established facts (word meanings), and me going against you.
I'm actually surprised I didn't already notice it.
That you're incompetence knows no bounds? Or that you try to argue everything for the sake of it, and still get owned?
