Answer 1

It is much more faster. Check this out:

var list = Enumerable.Range(0, 1000).ToList();

var stopwatch = new Stopwatch();

stopwatch.Start();

for(var i=0; i<1000000; i++)
{
    var c = list.GetRange(0, 100);
}

Console.WriteLine(stopwatch.Elapsed);

stopwatch.Restart();

for (var i = 0; i < 1000000; i++)
{
     var c = list.Take(100).ToList();
}

Console.WriteLine(stopwatch.Elapsed);

Elapsed time:

List.GetRange() : 0.149 s

List.Take().ToList() : 3.625 s
