Now some personal observations.
Alcohol is good for light heating/cooking in reasonable weather.
You start to get problems when it is cold and windy.
You certainly need a windscreen.

Alcohol does not produce the same kind of heat that a pressurized white gas (Coleman fuel naptha) or kerosene stove will. This means you have to carry a bit more of it to heat up as much water or food.

On the plus side fuel alcohol (methanol, wood alcohol, methylated spirits, denatured alcohol) is usually easy to find and often fairly cheap.
The container for it can be very cheap. A lot of people use plastic bottles.

It does not stink up your stuff either.

You can find fuel alcohol as fondue fuel in grocery stores or as wood alcohol in hardware stores. One variety of gas line antifreeze is wood alcohol too.
Fuel alcohol should have less than 10% water in it.

Don't use rubbing alcohol (isopropyl). Rubbing alcohol normally has too much water in it and burns too cold. Isopropyl burns dirty with a lot of soot too.
If you can find Isopropanol pure enough to burn well, then it will be too expensive to use for fuel.

Next is that alcohol usually burns very clear. Most of the time you can't even see the flame, so some caution is required around it.

I like the penny and atom style stoves but the cat stoves worked well to.
When I was younger I used to just grab fondue burners when I saw them in thrift stores. They worked better than expected.
