Are jQuery selectors safer than DOM properties?

These 2 expressions do the same thing, but is one safer or even more efficient?

var indexedCellValue = selectedCell.srcElement.parentElement.cells[index].innerText;

var indexedCellValue = $(selectedCell.srcElement).parent('tr').get(0).cells[index].innerText;

(And getting the cell, selectedCell, the parent row, and indexing into the column of that parent row.)

Pure JavaScript will always be faster than jQuery, but with jQuery you guarantee that the code will work in most browsers.

With jQuery, you only select elements that have a parent tr. I also think that a clean version of javascript will work on firefox 9+, but not older.

, jQuery, parent() ( 5666, 1.9.0):

parent: function( elem ) {
    var parent = elem.parentNode;
    return parent && parent.nodeType !== 11 ? parent : null;
},

, parentElement, parentNode, ( Firefox, 9, , . : DOM parentNode parentElement).

, node DOCUMENT_FRAGMENT_NODE ( , , , - , ).

2.0, ( pimvdb), parentElement ( - commit):

parent: function( elem ) {
    return elem.parentElement;
},

JQuery

var indexedCellValue = $($(selectedCell.srcElement).parent('tr').children()[index]).text();

parentElement, innerText.
