I think I like the ride home better. My ride is like a big W so it is truly uphill both ways with a bonus hill in the middle. The difference is that to work is a blazing first mile and slogging uphill for most of the rest.
On the way home I reel back in all of that gradual uphill, so it's blazing fast for a longer distance with a really steep climb up the mountian on the last mile home. Plus on the way home, lots of cars are trapped in the gridlock. It's fun to laugh as you roll buy the steaming cagers, trapped in their own swill.
