Hi Don.
There are pros and cons. Kero burns hotter but will spread soot around the cabin if it gets a yellow flame or if somebody who does not understand it tries to light it.

With a metho stove that has the tank fixed at the back of the stove (Maxie Stoves) you have to keep adjusting the gimbals to compensate for the changing weight of metho in the tank.
MorningBird fitted an Orrigo metho stove before we did the LHI trip 2 years ago. It is a very good stove being easier to use and virtually maintenance free. The flame is not as intense as a Maxie type stove because it is purely an evaporative type burner but that is somewhat compensated for by the larger diameter of the burner.
I found the odour from the Orrigo a bit pungent when it is first lit up as it is feul rich you might say. Once it is up to temp it seems to be ok.
I have more marine stoves than I can poke a stick at. I have just taken this beautiful Kiwi built Mariner stove out of my boat and we are going to use it in our outside kitchen at home.

For the size of my boat and the type of sailing I will be doing, it is really too heavy and if I need an oven I will use a hooded BBQ in the cockpit.
At home I have a Tudor Maxie 2 burner and grill gas stove. It works great but does not have fail safe burners so would never pass for a gas certificate on the boat.
Then I have 2 Maxie metho stoves. One is the smaller 2 burner and the other the larger model with 2 burners and grill. I don't think the grill is much use except maybe for toast.
I did a timing test between the gas Maxie and metho Maxie for boiling 500 ml of water. Gas 5 mins, metho 8 mins. I am still tossing up between gas and metho but either way I will have to build a gimballed platform for the stove.
On smaller yachts it is always a difficult choice on which kind of stove to have.
