The whitebox stove is sold more as a faster burner than an efficient stove. It burns water faster than most other meths stoves IME. I have a WBS, standard triad, AGG cookset which came with a can burner, Caldera cone for the AGG pot (3 cup one which is wide and low), a mini trangia and a smaller version of the proper trangia. If I had to choose I would go gas stove every time. My ancient primus can top stove is just so reliable with the PZ ignition it just works all the time without problems, even in quite low temps although that may need a fresh gas can with the better mixtures (i always try to use a primus gas can because IMHO they are better gas mix).
I have used all the meths stoves I have owned and can see how they all have a place which is determined by what works for the individual. i know this is not really advise but I can say that IMHO a stove that works for one person may not work for another. I love my caldera not least because it is the most efficient system I own for burning meths to boil water. I just find it too bulky in the plastic tube and I can't spare the cash to get the Ti version that is split so it fits into the pan.
For a while I used the WBS and I loved it but IME it is very unstable in the hills. Mind you a few spare Ti pegs and it is stabilized but at the weight of spare pegs or pegs removed from your shelter.
The triad is not very efficient but is solid and works. You can rely on it to work and it is stable.
The mini trangia (mine is a clone bought for a third of the price of a main brand version) is heavy and not very efficient. I am however learning to love my partner's trangia for car camping as a second stove for use with the remote gas stove (when we are on a quick overnight camp and trying to take less stuff only).
There is a UK maker (or was) from Scotland that made a stove not too different from the Starlyte. It used to advertise a lot in TGO magazine but I have not seen it for a few years (no longer get the mag). It is a round burner with three wire legs that swivel out to provide solid footing and pot support in one. kind of like the dragonfly multi fuel stove legs IMO.
One thing I do think, lighter stoves have less mass to heat up to reach the higher efficiency burn. IME it is part of the reason I have not got on with the mini trangia or the trangia burner without the rest of the kit just a stand. Also you can use Ti pegs as pot stands above a meths burner, just three needed, and they are then able to be put back to use for your shelter after they have cooled. Also pegs can be used to stabilize a can top gas stove.
Someone rightly said the pots do need to match the spread of the burner, or if you are making your own burners (think the OP does not like that idea) then you could make the burner patter to suit your existing pans. BTW those lightweight can burners can be made with any similar drinks cans should you crush the one you made earlier. I have heard of people not even leaving home with one but making it after finding two cans in the bin at or near their destination. Take the knowledge not the kit!!
