Pre-jQuery

I am working on a page with a small bit of JavaScript written by someone else. They are in the Pre-jQUery era. It’s all old and crusty code that is hard to read. I think I could have made the same stuff in jQuery using about 5 lines. jQuery just makes web page development so easy. It makes me annoyed just looking at this old stuff.
Example:

	var element = document.getElementById("foo");
var visible = element.style;
  if (visible.display=='' && element.offsetWidth != undefined && element.offsetHeight != undefined)
  {
    visible.display = (element.offsetWidth!=0 && element.offsetHeight != 0) ? 'block' : 'none';
  }
  visible.display = (visible.display=='' || visible.display=='block') ? 'none' : 'block';

in jQuery:

$("#foo").toggle()

Which do you think looks easier?
