There are any gain of performance or other advantages to do my POST request using ajax jQuery instead of do this requests using Html.BeginForm with a button to submit this request to server?

AJAX is to do background operations without refreshing the page. The question on what to use is around usability - not performance.

If you are going to stay on the same page but need to send (and receive) data from the server then AJAX is the way you do it. If you are going to end up re-rendering the page after sending data to the server then there is not much motivation for using AJAX

Why would you want to use jQuery for that?

If you are trying to prevent a CSRF you need to generate the token on the server and validate it on the server.

If you want to do an AJAX call and pass the token then you can included it the request by doing something like this
$(function() {
   $('element-that-triggers-ajax').click(function() {
         var csrftoken = $('input[name="__RequestVerificationToken"]').val();
         var data = {
              // your data here
              __RequestVerificationToken: csrftoken
         };
         $.ajax({
              url: '/path/to/svc',
              data: data,
              type: 'POST'
         }).then(function(resp) {
             // process return
         });
   });
});
