I like them all, man. Mood is a factor. That being said, when I just want a no nonsense shave, La Toja and Haslinger are as consistent and reliable as they come.
Haslinger. It's a small puck that fits well in a shaving mug. Costs about $4.50 if you buy from Euro vendors. I get several different varieties at the same time.
Also Speick stick. This is especially good for traveling.
