I personally like alcohol stoves because of their simplicity and reliability, in addition to their light weight.
To me, the packafeather is too complicated and fragile. There are too many parts for my liking. Now bear in mind, I have never used one, and my backcountry cooking is limited to boiling water for my food.
My favorite alcohol stove is the cat food can stove. It is one piece, inexpensive, nothing to clog or break, it is it's own potstand, and takes about 2 minutes to make.
Use a 3 oz. cat food can ie. "fancy feast" and punch 8 holes around the middle of the can with a paper hole punch.
It's that simple!
