I have used my alcohol stove for what will be the entirety of my AT hike (sections). I've tried the pocket rocket, i've tried wood stoves, and they each have their uses. But for me, I keep coming back to the Alcohol stove for it's simplicity and performance. I've used it from single digits to well into the 90s and it has never let me down. I've also used my PR in low temps and it's been almost as good.
If I were hiking solo and not cooking for 5 I'd probably use the PR for the easy of use (screw on, light and go) but for heating a 4 liter pot alcohol cooks more evenly for me (I don't just heat water).
So I'm not bashing or even degrading other stoves. Just pitching my voice into a chorus of others who say alcohol is a perfectly viable AT stove for thru or section or even day hikers.
