When was Darth Maul in his prime?

Phantom Menace. During this time he is in constant practice, confident, and most of all is cool, calm and calculating when it comes to battle. He uses strategy and guile.

After this he gives up all of this for blind rage and fury. Sure his saber skills may have been more honed later on than in PM, but there's no constant practice, no confidence, he's mostly angry all the time and doesn't care, he just throws himself at his enemy. Most of all he loses all of his strategic thinking.

Therefore PM is his prime.

He's factually more powerful in the Force in TCW, but that may not necessarily mean he's better in everything compared to his TPM incarnation.

He's certainly more 'measured' in TPM. Not some blood thirsty animal like in TCW, although he did come back in Rebels as a beta male. Too much fluoride and GMO's

Like I said, he improved his powers and lightsaber skills, but he didn't use these well, like he did in PM.

Once fact if his TCW incarnation met Qui-Gon Jinn, I think the Jedi master would win.

Definitely not, lmao.

Highly unlikely. Even Dooku vs. Yoda in sabers lasted under 30 seconds.

I mean, if you play out the conversations that are had in the meantime I'm pretty sure you can gauge the minimum time taken for the fight...

Edit: Although you're probably referring to a different fight.
