Palmolive and Wilkinson Sword are my 2 favorites. I strictly face lather and it's just more convienient to use a stick than to have a soap bowl for each different puck taking up space.
I've only used Arko sticks & really like it. I found out about sticks thru this site, too. Made the leap on an Arko purchase - I was a bit hesitant at first since you can pretty much only get them in larger quantities. What if I didn't like it? I figured out the internet weirdos who seem to love the stuff would take it off my hands. As it turns out, I'm one of those internet weirdos now.
I only face lather, so just doing a simple face rub w/ the stick & lathering up w/ my brush works quite well. Sticks are great for travel, too.
