I'm well aware of the distinctions between those items...
My experience with Johnson, at least on the commercial side, is that they have a substandard product comparatively to others on the market. The features, operation and reliability are such that many have started using them as door stops, boat anchors, etc. due to being able to purchase radios from other manufacturers that are a thousand times better.
Just an opinion from a man who has seen a lot of Johnson's junk over the years...
