Once you get into the pricey stoker boilers, the difference in what they burn isn't going to be big enough to even consider. The installation will probably have a lot more impact on how it performs and economy of operation than who made it.

Find an excellent used or re-manufactured boiler, any of those mentioned will work fine, the cheaper the better. Take the money and spend it on a great chimney and plumbing. Even a twenty year old coal boiler is going to have a greater life expectancy then the liquid and gas units coal competes with.

The KA-4 and KA-6 appear to use the exact same stoker, just the boiler size is different. You might end up with better efficiency on the KA-6 due to better heat transfer to the water due to the increased surface area. I'd guess they would both idle at the same rate, so that shouldn't be a big difference.

I heat about 4,000 Sq feet of poorly insulated, drafty, old 1910 wood house that gets a direct west wind off Lake Erie with an Axeman-Anderson 130 and 1020 sq ft of old cast radiators.

It does pretty well except on a windy sub zero day, but there aren't many of those.
