Try before you buy
I agree with Nessy [edit- and Alpha]- try everything you can get your hands on before buying. Buy whichever one you like the most on the water, easiest to get it go where you want, is the most comfortable, fine swimming out of, etc.
I always recommend for someone's first boat to buy used. The latest, greatest boat (i.e. new) costs more and won't necessarily help you learn the very basics any quicker (how to sit in the boat, how to hold a paddle, how to swim out of the boat, paddle strokes, bracing, etc.). In some cases an older style boat may be better (i.e. older boats are typically longer, and longer boats are, everything else being equal, easier to roll and are quicker).
Plus, in the unlikely scenario you decide that this isn't what you want to be doing, it won't be as much of a financial loss.
Every major brand you mentioned has a cultish following, as with any sport.
To more specifically answer your question- People seem to progress in the sport in two different directions over time (though many chose both directions)- playboating, or creeking. Two different ends of the spectrum in a way. River runners, and river runner/playboats are sort of the inbetween categories in my opinion. I'd recommend looking at those genres of boats for a first boat.
Cheers and Welcome!
