We installed two different Envirolet (Canada) units in a detached building when we lived in Juneau. High quality units - no complaints there. But the liquids overwhelmed the capacity of the units to evaporate to a useful level - always soggy and relatively cool in coastal Alaska.
Point - if you are going to frequent coastal or humid environs, particularly if you will not be hooked up to shore power to run the heater/fan assemblies if included - consider the urine separator designs.
Disclaimer - haven't used any of the models you listed. Others will know better how they function in humid climes.
