nodeType
82794064.0 Ops/sec
instanceof
51139012.0 Ops/sec
nodeType literal

Script Preparation code:
var xs = []; var n = 0; for (let i = 0; i < 1000; ++i) { xs[i] = (Math.random() > .5) ? document.createElement(`a`) : document.createTextNode(``); };
Tests:
nodeType
n += (xs[(Math.random() * 1000)|0].nodeType === Node.ELEMENT_NODE)|0;
instanceof
n += ((xs[(Math.random() * 1000)|0]) instanceof HTMLElement)|0;
nodeType literal
n += (xs[(Math.random() * 1000)|0].nodeType === 1)|0;
