In my opinion after having owned both styles, the drill-type header is superior to the no-drill style. It's faster to use and more secure. I installed a drill-style header into my previous '97 TJ and loved it. Then on my '04 I first went with the no-drill style but quickly learned to hate its slower more difficult to use design when compared to the easy and quick slide-in from the side design of the drill-style. I converted my '04 to the drill-style header and love it. The plastic trim around the windshield has to be temporarily removed, it just snaps on and off, but it's an easy job.
