Optimus Crux

The Crux from Optimus. The burner head folds down to a very flat profile and weighs only 85g.

The Crux was my back-up stove during the New England bicycle tour 2016 and the Grand Canyon trip 2017.
The cook stand is only suitable for smaller pots. The point of balance is high up. Particulare with a full pot on top there is a risk of tipping it over. One must reach right underneath the flame and hot food to turn the regulator. Therefore the additional tripod, which clips underneath the cartridge, is a must-have safety feature.
Not a 4-season burner.  At temperatures near 0°C the fuel may no longer turn into gas.

Still a great little back-up stove anywhere with not so cold temperatures.

Optimus Vega

With 180g the Vega is twice as heavy as its feather-weight brother, the Crux, but the low profile and the wide cook stand makes it suitable for larger pots and pans. There is less risk to tip pots over and spill hot content. Also the regulator is not directly underneath the pots. Which makes it's saver to handle.
Biggest advantage - it is a 4-season burner. Turn the gas canister upside down, on the integrated stand, and liquid fuel will flow into the coil above the burner head, where the heat will turn the liquid into gas. This should keep the burner going even at solid temps under 0°C.

The Vega gas burner from Optimus was my stove of choice for my tours in 2017: Hawaii, Iceland and Grand Canyon.

Bushbox Pocket Stove

The Bushbox is a multifuel stove from the german company Bushcraft Essentials. The stainless steel version weighs 270g. 

It's designed to burn wood, but will burn any kind of organic material and can also be used in combination with the Trangia burner.
It is rather small, but with the right technique it's absolutly possible to keep a small wood fire going to cook food on it.
For more ambitious cooking I'd recommend the Bushbox XL (see below).

Bushbox XL, Titanium

With 500g it is the heaviest of all my stoves, but the most capable, when it comes to ambitious cooking projects. The stove may be somewhat heavy, don't need to carry fuel. Simply collect it as you go. So it is a draw. If you know the how-to of setting up a solid little cooking fire you'll enjoy cooking real meals.
I cooked pretty much all my evening meals on the Bushbox XL during those 6 weeks traveling New England. 
I had the Optimus Crux as back-up stove with me, but used it only in the morning to brew tea or coffee.

The Bushbox XL from Outdoor Essentials was my main stove during my New England bicycle tour in 2016. 

Fried scallops.                                             Scallops with linguine.                            Stir fried vegetables.                               Vegetable-pasta pan.                             Green asparagus with scallops.

Trangia 27 Cooking Set

The Trangia 27 was my cook set during the Alaska 2012 backpacking trip.

My Trangia set is 25 years old. The complete set consists of 2 pots (1L), 1 frypan (18cm), 1 kettle (0.5L), upper and lower windshield, an alcohol burner, a pan grip and a strap. This whole set-up weighs 1050g. Mind you, the materials of the latest Trangia 27 version weigh around 200g less.

The burner uses methylated alcohol as fuel. It is nearly indestructible, easy to use, burns noiseless. It doesn't give off toxic fumes and like fondue burners can be savely used inside of rooms.
