Combustion differences between rocket stove and gasifier woodstove/boiler

I was wondering what the burn process looks like in a rocket stove vs a gasifier boiler or woodstove marketed as 'gasifier'.

My understanding is the rocket stove design causes such a hot burn that any smoke and particulate is simply burned due to the high temps.

My understanding for wood stoves or boilers marketed as 'gasifier' is that they limit oxygen during the burn to cause volatile gasses to seep out of the wood at high temps, then burn those gasses off.

Which combustion is more complete? Which renders more useable heat btu's per unit wood?

Design-wise, it seems like a rocket stove is simpler to build as a DIY'er... coming from a guy who has built zero wood burning apparatuses :)

But conventionally speaking, it seems like the woodstoves and woodboilers tie in better to new house construction (makes the people at the department of making you sad less likely to make you sad). I like the idea of a gasification wood boiler plus thermal storage tank for heating a house, domestic hot water, the shop, heck - even melt the ice off the driveway in my old age.

Hi Aldo;
I had to look up wood-burning gasifying boilers, and then I had to read about indoor and outdoor boilers.
Comparing them to a Rocket mass heater is like comparing apples and oranges.

The gasifiers sound very cool.  In a suburban setting, they might be a very good choice.
Particularly the indoor burner sounds like a winner.
A couple of thoughts about them.
What do they cost?  $20,000- $40,000  I do not know but it is much more than any RMH.
What is the installation for the rest of the home?  Do they use radiators?
What happens when the power goes out?  

On the RMH side, things are completely different.
Massive amounts of oxygen are supplied to create an inferno of fire with temps from 1800F-2000F
Almost all particulates are burned down to fly ash.  That heat is then stored in a mass to be slowly released in your home.
Costs are low depending on what style of RMH you build.  
No electricity is needed at any time.
No separate installation is needed for the rest of the home.
A centrally located mass and an open floor plan help keep the whole house warm.

In many suburban areas, you might be better off with the gasifier. I do like that it is a wood burner!
In a more rural area, the RMH would be my choice.

EDIT) I forgot the most important feature of an RMH.  
Hanging out sipping your coffee warming yourself, petting the cat who is warming themselves...
There is no substitute for the awesomeness of a wood stove... nothing compares!
