Yeah, that's a good point with gapping issue between the 6097's and the 3330's. When I gapped the 3330's, you could see a noticeable "bend" at the tip (can't remember what that tip is called). Anyhow, the usual 90 degree angle became a little less. I'm sure that somehow takes away from performance?
BTW, check the gaps on the 6097's anyhow (even though you PROBABLY won't have any problems). I had a friend who was stuck with a plug that appeared to have been dropped, and made gap slightly smaller.
Again, if possible, try out both. If I have to go with one, I'd stick with the 6097's. The rough idle made my car sound untuned, which was embarrasing at stop lights
