Wind is also big factor that affects fuel consumption. 

The  BRS-3000T is noted for terrible wind performance so to use it effectively it must be shielded from wind which is generally not to hard.   However, do not to use a full wind shield since this will allow the canister to overheat and explode.   

The  BRS-3000T is  also noted for quality control issues probably because it is made in many different factories.  It is a design more than a brand.  The typical failure is that the pot supports just bend when they get hot...probably this can be avoided by not running it on full. 

That said many people have through hiked using these stoves and they are extremely light weight

The Soto Amicus supposedly performs a much better in windy conditions and compares favorably with the MSR Pocket Rocket Deluxe which copied Soto's Windmaster burner design which many consider to be the "best" performing backpacking stove available.  I have not compared these personally.  The Amicus does not have a regulator like those stoves.    Regulators allow the stove to operate more consistently as the pressure in the canister changes.  This may provide slightly improved cold weather performance but the main benefit is just a more predictable control setting.
