Jerry -
I had the heated liners, tried a borrowed pair of Gerbing classics for a while, and recently got the G3. Haven't had an opportunity to try the WarmNSafe.
The heated liners were OK, but the bulk of them under snowmobile gloves had my dexterity almost to the level of wearing mittens. The warmth riding to work in the mornings was wonderful for riding to work, but flipping switches could be cumbersome. I couldn't imagine going without a controller, as a couple of times I rode with them under regular 3-season riding gloves and I got burned where the liners bunched. I don't think I ever turned them up above mid-range.
The Classics were great and the only reason I didn't buy a pair was that I already had the liners and cheaped out. I didn't use them on the 20s-F days, but they were plenty warm in the 30s and never probably needed the controller above mid-range.
I just got the G3s recently, so temper what I'm going to say by knowing that so far I've only used them in the 40s just to play and see if they worked. They rock. I have both heat and dexterity. Obviously, the controller never reached the mid-point due to the air temps. I think the reason they are supposed to draw a little more is because the Classics covered less area with wire, while the G3 has less insulation, so has less unheated space between the internal wires. The net is that both are plenty warm, but in slightly different ways. The only times you notice the difference are (1) when not running the heaters, the Classics are warmer, and (2) the G3 are more like wearing a lined 3-season glove, so you don't think about them when going for switches, your visor, or anything else that needs finger-level dexterity. If you're down this way or we hook up sometime soon you're more than free to try them.
Another guy had a question about heated grips. To me, they were OK for shorter rides or when the temps stayed above about 40, but just didn't cut it when you're in the cold for a couple of hours commuting every day and it's colder than that.
