It depends on your needs I suppose.

It's the one you have with you at the time.
You took the words right out of my keyboard! I'd have written exactly that this morning if the forum hadn't booted me off for the umpteenth time this year.
There's no 'best' taking into account Dewi's list of criteria, at least until Sunndog's extra information is added to the mix, plus quite likely Sandbender's too.
For example a wood-burning stove might not be too good if you're only going to be staying in a bothy, and
if I were going to walk the Appalachian trail for a couple of months I don't think I'd want to carry enough gas cylinders for the trip.
I have literally dozens of stoves, and about the only ones that I don't often use are those that run on gas.
Any other fuel is fine for me, although of the liquid fuels I tend to use alcohol the least except for
(a) priming burners (for which I always use alcohol),
(b) general fire-starting and
(c) first aid, for which you'd be crazy to use petrol.
Of the liquid fuels I use what I'll call 'petrol' (which for me is mostly Aspen 4 thesedays) the most.
I use wood a lot in my Ghillie, and I use that even on bike journeys.
If I'm going to be in a camp somewhere for any great length of time (more than a few days), wood will be my fuel of choice for more or less everything.
The best liquid fuel IMO is undoubtedly paraffin.
The worst for efficiency - this isn't an opinion, it's the calorific content - are the alcohols.
But that isn't the question you asked.
All my cooking at the weekend was over a wood fire, but I made several mugs of tea using a Primus 96 running on paraffin but primed with alcohol.
The wood made me smelly, the paraffin ran out half way through making water for a hot water bottle.
But I didn't really need the hot water bottle, I had more paraffin anyway, and I could have just used the camp fire instead - I really wanted to know how long it would run for.
The burgers that I've just finished (and very good they were too), I have to admit, were cooked using electricity.
If I have a favourite portable stove it's probably an Optimus 110B, but the various 8s run it a good race and I love them all really - even, much to Big Si's disgust, the British Army Number 2.
