More than you wanted to know.

In order of use:

Caldera Cone with 600 ml Evernew pot:
Pros:
The Caldera Cone fits into the 3 cup Ziploc,
Wide pan is THE most fuel efficient of all the Caldera Cones,
No pot lifters needed,
Very stable..
Cons:
Takes two burns to boil 12 oz. for food and 8 oz. for beverage.

I use a 16 oz. solo cup inside the 3 cup Ziploc with cozy to do freezer bag cooking. After hydration the bag can be turned down over the sides to make eating easier. I use a JetBoil spoon.

Caldera Cone with Trangia 28:
Pros:
This kit will FRY food!!!!!,
The Caldera Cone fits into the 3 cup Ziploc,
Very stable with pot,
Cons:
The skillet is a bit unstable,
Need to use pot lifters.

This is the kit I use when cooking in the pot and frying. Yes, Rand will make one if you ask.

Caldera Cone with MSR Titan Kettle:
Pros:
Can boil enough water for both food and beverage,
Very stable,
No pot lifters needed,
The design of the Titan Kettle is classic and aesthetically pleasing.
Cons:
The Caldera Cone does not fit into the 3 cup Ziploc,
Pot handles tend to get hot.

The solo cup and JetBoil spoon are also a part of this kit.

This is the Ti Caldera Cone complete wood burning setup. The firebox is big enough that it does not require constant attention. This is the stove I use when I want to primarily use alcohol, but have the option of melting snow.

Trangia 27-5:
Pros:
Stove is elevated so it can be used on picnic tables,
Use a metal shovel for a base and cook on the snow,
Very stable,
Very wind proof,
Reliable - no moving parts.
Cons:
Heavy,
Need to carry the burner and fuel in pocket,
27.0 oz.,
Need pot lifter.

This is the stove I use to cook lunch when nordic skiing. A fun stove to use.

GSI Minimalist pot and V8 stove:
Pros:
The pot lid works well as a beverage lid,
Has a new and innovative pot lifter,
Inexpensive,
Needs a very small flat area to set up.
Cons:
Not as fuel efficient as a Caldera,
Needs a pot lifter.

Made a replacement cozy for the pot from a ccf pad. Used when I want to make a cuppa on day hikes. Just a simple hardware cloth stand and Al flashing windscreen.

Optimus Nova:
Pros:
High BTU output,
Simmers well,
Robust all weather stove,
High energy per ounce content of the fuel,
Field repairable,
No plastic components,
Good for melting snow.
Cons:
Heavy - the stove alone weighs more than my normal complete kitchen,
Fuel is not environmentally friendly,
Priming is time consuming, messy and maybe dangerous.

I have owned MSR Whisperlite, DragonFly and SimmerLite but had a plastic pump failure and cooked over a camp fire for two nights. Now use an Optimus Nova for winter overnights.

Snow Peak Giga Power with piezo - 3.7 oz.:
Pros:
Easy to use,
Simmers well,
Easy on/off makes it fairly fuel efficient,
Two or three people can share this stove conveniently.

Cons:
High profile is unstable,
Wind screen is difficult,
Small flame pattern makes hot spots on the pan,
Empty fuel canisters are not environmentally friendly,
Need to keep the canisters warm in below freezing temperatures.

IMHO the selection of the gas canister blend is more important than the stove. I look for canisters with a high percentage of propane and isobutane rather than regular butane.

Current test stove:

Emberlit-UL wood burner.

Stoves I do not use and why - in no particular order.

Caldera Cone and antigravity 3 cup pot - kept at the office to cook lunch.

Fosters Caldera Cone - nice little setup but wider pots perform better with only small weight penalty and the system is a little fussy to setup and take down.

Ultralight Outfitter Fosters can System - nice stove and has the burner off the ground, but wider pots perform better with only small weight penalty.

Compact Caldera Cone with Mountain Laurel Designs 850 ml pot - nice set up but less fuel efficient the full sized Caldera Cone and the tent stakes used for the pot support are a bit fussy.

Bushbuddy Ultra with Snow Peak 900 ml pot - nice stove, but the small fire box requires constant tending to melt snow.

Four Dog Bushcooker LT with Vargo Ti Lite Mug - nice stove that works well but the fire box is even smaller than the Bushbuddy Ultra.

T’s Side B stove - works great, but unstable.

Brasslite Turbo I - adequate stove, but unstable.

PackaFeather FeatherFire stove - best temperature control I have ever seen on an alcohol stove, but that is not a feature that I use.

Brasslite 600 ml Caldera Cone - nice system, but the Evernew 600 ml has the same features, but the wider pot performs better.
