SharePoint PowerShell Document Library properties

I'm pretty new to PowerShell and try to collect the following data about every document library in a site-collection:

1. Document Library Name
2. Created Date
3. Content Type

Are there any general improvements i could do to the code? Are there any other way of getting the name of the content type?

add-pssnapin microsoft.sharepoint.powershell -erroraction SilentlyContinue 

$siteURL = "https://contoso.com/sites/projects"
$site = Get-SPSite($siteURL)

foreach($web in $site.AllWebs) 
{
    foreach($list in $web.Lists)
    {
        if($list.BaseType -eq "DocumentLibrary")
        {
        $listName = $list.Title
        $listCreatedDate = $list.Created
        $listContentType = $list.ContentTypes
        $listContentTypeName = $listContentType.Name

        write-host "List name: $listName"
        write-host "List created: $listCreatedDate"
        write-host "List content type: $listContentTypeName"
    }
}
}
$web.Dispose();
$site.Dispose();
