Ride naked in the snow Howie. Prove that your Super Tough.
Not being Super Tough I like the heated gear. Don't use the heated pants often though. Lined jeans with good long johns beneath are good to 30 degrees or so, especially with the rain gear pulled over them. Surprisingly that combination really is less cumbersome than dealing with the heated pants. All day in less than 35 degree weather I'll wear them. Local riding just never mess with the pants.
I've had the jacket liner for several years. Under only a middle weight jacket it's good to 25 degrees or so. The heated gloves start losing the battle at around 25-30 also. They make riding days easy that otherwise would not be.
Have read of several who have sent their gloves back to Gerbing (gloves same vintage as mine) for some sort of an upgrade to increase their output. These get me through weather as cold as I'm going to ride for any real distance though. So have never messed with it.
Do have a Powerlet outlet mounted as a hard point under my left leg. Makes for an easy connection point for the gear. Don't know anything about their micro-wire system (in the clothes) other than what's on their website. That is newer than all my gear.
