Tanjiro commences the Sun Breathing: Thirteenth Form against Muzan.

The fifth form accomplished exactly that. Called the Blessed Rain After the Drought, it's an attack meant to decapitate enemies without causing any pain, which allows enemies who have surrendered to die a graceful death without feeling any unnecessary pain.
Initially, Tanjiro's accuracy and strength were not up to the mark, which is why Muzan was able to avoid his attacks. However, Tanjiro accurately performed the thirteenth form and inflicted a ton of damage on the Demon King.
1/10 Tenth Form: Constant Flux/The Dragon of Change
The most powerful water move in Tanjiro's current skill set, this is a form that gets more and more powerful with each rotation that he puts in. It's number one on the list because it has, theoretically, no ceiling when it comes to its intensity.
This mastery allowed Zenitsu to form a Seventh Form of Thunder Breathing that is unique only to him: Honoikazuchi no Kami. While this move might seem similar to Thunder Breathing's First Form, the speed and power of this technique are on a whole new level.
Tanjiro isn't Faster Than Zenitsu, not at all. He is Strong but Slow. So, Zenitsu Will Probably Chop Him Down to bits before tanjiro even pulls out his sword properly.
Tanjirō's resemblance to Yoriichi (like from Muzan's perspective), would trigger his memories and cause him to accept death. AND since its against Kokushibō and not Muzan, there's not poison that'll mess him up. So I would say Tanjiro would win.
The Thirteenth Form of the Sun Breathing Style is unique in the sense that it doesn't really have a name of its own. Rather, it's a combination of all the twelve forms present in this style, used in succession to maximize their power. This move was devised by Tanjiro solely to defeat Muzan.
The Eleventh Form is an original technique created by Tomioka, which is also referred to as Dead Calm. While there are ten known and established forms, the Eleventh is purely Tomioka's addition, allowing him to negate the attacks of the enemy by ceasing his own movements.

So in a nutshell, Zenitsu wasn't able to master the other five forms, but later in the Infinity Castle Arc, during the battle with Kaigaku, Upper-Rank Six Demon, he created a Seventh Form: Flaming Thunder God.
Thunder Breathing has 6 standard forms in total, with the first form said to be the foundation for all the other forms.

1) Inosuke Hashibira
Although Inosuke possesses immense strength and endurance, he's no match for Zenitsu's insane speed and his Thunder Breathing.

When combined with God Speed, his power and strength increase, giving him the ability to defeat demons like Kaiju, from the Upper Moon Six.
When facing Kaigaku during the Infinity Castle arc, Zenitsu debuts his brand new exclusive Seventh Form to Thunder Breathing. With this, Zenitsu finally has more than one tool in his arsenal and has overcome his own personal doubts and fears.
