I ran in the expediting world for a few years, hauling time-sensitive cargo around North America. A
lot of my fellow drivers used diesel heaters, usually Espars D2s and Webastos, often self-installed in everything from GM vans like mine to Sprinters etc.
Almost universally, the Espar users had less problems with general use, soot buildup and cleaning. Even in warm weather they would run the heater for an hour every once in awhile. Webasto users seemed to have more problems in general, a trend that carried over into the van world when more and more "vanlife" folks started installing diesel heaters. More than one Webasto user switched to Espar. This was a few years back, and things may have improved since then.
Here's a great link I've had for years to a DIY install of an Espar with a mess of links to other resources:
