I was wondering if there is any known difference (mostly performance related) between those two methods of retrieving all children of a given Item.

The first one will give me all levels of children in one shot.

On the second approach, I have to build some code to recursively get the same result, since Item.GetChildren() only returns the first level.

I don't know why but I had a feeling that the Item.Axes.GetDescendants() was always slower, but using DotPeek to see what is going on under the hoods now I'm no longer sure.

#Item.Axes.GetDescendants()

Item.Axes.GetDescendants()

It uses the item.Children property.

Which ends up calling ItemManager.GetChildren(this._ownerItem, (ChildListOptions.IgnoreSecurity & options) != ChildListOptions.None ? SecurityCheck.Disable : SecurityCheck.Enable).InnerChildren

#Recursive Item.GetChildren()

Recursive Item.GetChildren()

Which is also ItemManager.GetChildren(this, (options & ChildListOptions.IgnoreSecurity) != ChildListOptions.None ? SecurityCheck.Disable : SecurityCheck.Enable, options)
