Jammers vs Briefs

Because of the Tech suits that a majority are now not allowed in competition the old threads don't provide much insight into the world of Jammers. I am curious as to what everyone is wearing nowadays and why. When I stopped swimming in 1995 the HS state meet was 100% briefs and now from what I read it would be more like 20%. I always went with the less material the better philosophy so my meet suit was smaller and tighter and my state meet suit was even smaller and a "paper" suit. For practice I would wear 2 or 3 suits with the bottom layer in decent shape and the others progressively more ragged. Since I have been back I have been wearing a square leg speedo drag suit mostly because it is slightly less "old man in a tiny suit" then a true brief but still allows me to actually swim without feeling like I am pulling a bucket. I just tried a TYR durafast jammer to see what all the hype was about and it seemed to have as much drag coefficient as my smaller drag suit. My wife seems to think walking around in a jammer is less "European" then my drag suit but I counter with it is more revealing in an impressionistic sense. So my question is Jammers or Briefs and why. I missed the how and why Jammers were made popular in the revolution of the sport and now fail to see the benefit in them. Tech suits aside please.
