Xamarin.Forms Use Plugin or DependencyService

Question

I am working on Xamarin forms project that targets three platforms (Android, iOS, UWP), and I was wondering which better to use Plugins or it's better to use DependencyService

https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/dependency-service/introduction/

if my Example I need to retrieve some data from each platform like Version, DeviceName, OS ...etc

I created interface

public interface IAppVersion
    {
        string GetAppVersion();
        string GetDeviceName();
        string GetOS();
        string MailEOL();
        int GetOSMajorVersion();
    }

and start to implement my interface in each platform

[assembly: Dependency(typeof(VersionDroid))]
namespace CrewBriefingForms.Droid
{
    public class VersionDroid : IAppVersion
    {
        public static bool FormsInitialized = false;
        public string GetAppVersion()
        {
            Context context = Forms.Context;
            string version = context.PackageManager.GetPackageInfo(context.PackageName, 0).VersionName;
            return version;
        }

        public string GetDeviceName()
        {
            return Build.Model;
        }

        public string GetOS()
        {
            return "Android SDK: " + Build.VERSION.Sdk + " " + Build.VERSION.SdkInt.ToString();
        }

        public int GetOSMajorVersion()
        {
            return (int)Build.VERSION.SdkInt;
        }

        public string MailEOL()
        {
            return System.Environment.NewLine;
        }
    }
}

what I find plugin do the same job, should I go for using a plugin or implement my own code

and one more question according to code review should I create many interfaces as my interface name called Version and I ask for more than the version
