It is a bit simplistic to say that there is 'no definite answer - just opinions' to these questions. In the end everything comes down to opinion, of course, but many of the questions you pose seem to me to have answers like:
If 'x' is more important than 'y' then go for A, otherwise B.
For instance, if cost is most important, go for the GC radio, but if better trim and looks are more important, go for the Planet. Unless ground rules like this are specified first, you end up with an interminable argument where the protagonists are arguing about subtly different things....
