Benchmark: getComputedStyle - call + access variations.

HTML Preparation code:

<style type="text/css"> .ok { gap: 20px } </style>
<div class="ok"><div>one</div><div>two</div></div>

Script Preparation code:

var okThen = document.querySelector('.ok');

var alwaysGet = (function () {
   return function () {
     return window.getComputedStyle(okThen, null).columnGap || window.getComputedStyle(okThen, null).gap;
   }
})();

var mostlyGet = (function () {
   return function () {
     var got = window.getComputedStyle(okThen, null);
     return got.columnGap || got.gap;
   }
})();

var stashGet = (function () {
   var got;
   return function () {
     got = got || window.getComputedStyle(okThen, null);
     return got.columnGap || got.gap;
   }
})();
