Hey I just found a more efficient way to kill it and in creative, I managed to do it in less than a minute.

I used a lot of beds in the Nether. The beds' explosion deals a lot of damage to the Wither. But in survival, you do have some downsides.

First of all, beds can explode, and you need to find a way to resist the damage. You can use golden apples or enchants or blast resistant blocks. (e.g. Obsidian)

Secondly, beds aren't stackable, so I guess you will have a whole inventory of beds just to kill one wither.

But if you can deal with these problems, then you can kill it in 1 minute.
