I used one of these exclusively to cook on an 8 day bike packing trip about 15 years ago. You can't beat it for weight and size efficiency IMO.
I also had the fuel bottle leak in my pack (and the friend I was hiking with forgot his gas canister), fun times.
Now I'm mainly using a small gas canister (100g) and a small titanium burner (20g I think?) and I find the (small) added weight worth it.
Alcohol stoves are great if you have time and it's not too cold, plus it's easy to take only the fuel you need. With gas canisters you have to take the whole thing, and after a while you may end up with several partially empty canisters and have to weight them to take the one with the amount of remaining fuel the closest to what you'll need for your trip. I have 3 or 4 of those at the moment.
There's quite a spread between the heating output of alcohol stoves. # Of holes, alu vs. Ti vs. brass, filler materials (if any). Some have simmer rings, some don't. Outside temps matter too.
The trick is to use it a # of times before you go out camping / backpacking. So that you're familiar with its behavior.
Disclaimer: cooking daily on a deluxe model (Origo 3000). Safest method to cook on a boat.
Propane/butane burners are easier to regulate, but these gasses have the nasty habit of sticking to the floor. So a leak could cause a deadly explosion (which happens semi-regularly).
That Origo: I could flip the whole thing over while burning & it wouldn't start a fire. Can't remove the burner from the stove while it's on due to a safety catch.
Also have a Trangia stashed somewhere (just the burner not pots/holder). Also used many times.
Both Swedish design & highly recommended. Cheap/ubiquitous fuel is a big plus too. Sadly the Origo isn't made anymore afaik.
It takes 7-10mn to boil the water I need for food + a coffee, while using my gas burner it takes 2-3mn.
One issue I forgot to mention is that it's almost impossible to get the remaining fuel in the burner back into the container.
The Origo 3000 you mention looks really cool!
I own a Chinese manufactured petrol stove which works ok. It’s a pain to light however. Never used an alcohol stove myself but I have hiked with a friend using one and that seemed painfully slow. Can stoves seem like a novelty to me. A nicer burner is not particularly expensive nor is it that heavy.
But it's a compromise, they all have their pros and cons.
