In theory they are the same. Update calls save under the hood. The difference is that update checks for guarded properties while save does not. And the syntax is different
Oh and save works for both create and update.

What is the difference between save() and update () method ?
What's the difference between save() and update() and what's the best use case for each of the method. I read the Laravel docs but I feel I need more of a deeper understanding of the two methods.

@sinnbeck thanks but is there any best use case for the two methods?

@atoagustyn it depends on the situation. For instance I often get the data I want to update from validation. Here it makes sense to just pass it to update
$post->update($validated);
But if it is just setting a single column, I would use save
$post->slug = $slug;
$post->save();

use update where you already have the data in an array or collection that matches your model
use save when you already have the model in memory and need to update some of the attributes
Don't over look the fact that update can work directly without loading the model first, eg
Post::where('id',$id)->update(['status' => 'published']);

Illuminate\Database\Eloquent\Model::update(array $attributes = [], array $options = []) is a shorthand for
$this->fill($attributes)->save($options);
update checks for guarded properties while save does not.
This does not look correct.

This is not correct. The update method on the Model object is different than the update method on the Illuminate\Database\Eloquent\Builder object.

@debiprasad I disagree. Yes they are different methods, but the OP just said difference between update and save. No distinction made between Builder and Model
Level 2
@Snapey Yes, OP talks about the difference between Illuminate\Database\Eloquent\Model::save and Illuminate\Database\Eloquent\Builder::update.
I just clarified that both the update methods are different.
