We went with the 28BHBE, but it wasn't a snap decision. Aside from some minor differences, they are functionally close enough for us. From a strictly utilitarian standpoint, we viewed them as virtually identical for our intended usage pattern. Tank size didn't matter because we didn't intend to boondock, and so far we have not been to a park without sewer service. The thermostat wasn't that important to our decision (but maybe should have factored), large fridge is nice but not totally necessary, I could install rams under the bed if I wanted to, I wouldn't call that little fan in the bathroom a selling point, and windows in the slide are nice but not a deal breaker.
Some of the items that made the decision for us were; the higher-end feel, the solid shower door, power jacks (esp tongue jack), power awning (we have no complaints and have had no problems at all), included TV, and the relatively small price difference between the units. These items coupled with some of the others from above kind of drove us to the 28BHBE.
Also, there was the subjective "feeling" factor. When logic has played out and you're still on the fence, go with what you feel. DW walked out of one and into the other 3-4 times, and the decision was made. I would have been happy with either one, so I'm all good.
