Ironknees, I personally use a drop tube so don't have direct experience in other techniques, but others have reported good success by filling the case with 1/2 the powder and tapping the side of the case, then pouring in the rest of the powder in and tapping the case some more. Another approach I've heard of is using a vibrating tumbler/case cleaner as the soruce of vibration to settle the powder. And finally I've heard of one person using an electric shaver as the vibration source.
From what I've read the drop tube is reported to be the most consistant assuming one maintains the same pour-rate of powder into the funnel.
By the way, from what I can tell the only real reason to use a drop tube or other vibration techniques is to get more powder into the case.
I'll be interested to see responses to your question from others.
