I have been meaning to post my experience with this but keep forgetting. Got on here tonight and the top post was about this same issue. So I made a quick video.

The only ignition coil I have had go bad was the number 8 cylinder coil. Which is the one that used to get water in it. The water damages the coils. Without this issue, quality coils should last as long as the plugs. 7/8 of mine are original! 185,000 miles.
