I don't find ramps any faster or better for that matter.
I just jack up one side of the car enough for me to get to the drain plug, I put a jack stand under the car for safety, but I don't put any weight on it, then I lower the car to get all the oil out, then jack it up again, put the drain plug in and change the filter. I'm usually done in 20min. most of the time is spent on waiting for oil to drain. Before it would take me about 10 min just to fiddle with ramps. Using the jack and jack stands may sound complicated and troublesome on paper, but it is really fast and not much work at all.
