I used a Kifaru small for the last several years but sold it this year and got the Seek Outside medium stove with a 7' pipe.
My thoughts:
Titanium pipe is harder to roll initially than SS, but after the first burn it's easy.
The SO stove is built MUCH tighter than the Kifaru.
The SO stove draws and burns better than the Kifaru because it is built tighter and doesn't draw air through the joints.
The SO is made from titanium instead of SS and is about a pound lighter.
The SO currently costs $25 LESS than the Kifaru.
Ths SO door opening is bigger, making it easier to use. The door itself slides on, meaning it removes completely, making it easier to use. The door fits tighter than the K, making it burn better.
The SO damper is awesome. It is a premade section of pipe with a sparkscreen and a turnable damper plate inside. It works great.
Take a drink for each time you see SO . jk
