I used the Glock loader for a while when I had some hand pain/strength problems. I found it worked best for me by just standing the mag on a table/shelf and pressing the mag loader down on top of it. Press the loader down until the top round is depressed far enough to start the rim of the next round under the feed lips, pull the loader up, push the round the rest of the way back under the feed lips, repeat. After some practice, you get faster.

For most young-to-middle-age folks with normal hand strength and dexterity, loading by hand without a loader IS faster.
Fastest method is pre-loading 10-12 mags before leaving for the range.
