I use both. Mostly front and a bit of rear for normal stopping and mostly rear for low speed stopping. I was taught 70-30 front to rear. The way I see it even if the front brakes have 90% of the bike's stopping power if you don't use the rear you're down 10% braking power so use them. For carrying a pillion too if you only use the front I've found a lot of headbutting goes on whereas using both keeps the bike more stable and stops the headbutting
