I had a 686, currently have a 586, and also own a GP-100.
586 no dash
GP-100:
The GP locks front and rear, and has lots of steel. When I test HOT loads, I use the GP.
The 586 and the 686s I've owned/fired have had great triggers. But when it comes to actual shooting I've found it makes little difference.
The extra cylinder hole in the 7-shot Smith kinda creeps me out. I like lots of steel around my .357, which is a very high pressure hand gun round, and a 7-shot does not have as much steel as a 6 shot. That does not bother me for target practice, but...
If I wanted a woods gun, I'm going to want a revolver stuffed with full power magnums. I'd have to give the nod to the GP-100.
What I'd really want is an N-frame Smith, like this 28-2:
You can beat a critter to death with it if you run out of ammo.
PS - Obscenity kind of bugs me too, even obscene Internet abbreviations. But then again, I'm old, and it's a free country. So far.
