Try them. Try them. Try them.
Asking us which keyboard you should get is like asking us to choose your favourite flavour of ice cream.
Everybody prefers keyboards with different touches, sounds and looks. That's why there are so many!
Ideally, find a place where you can try them next to each other. If that's not possible, try them wherever you can, take some notes about how you feel when you use them, then compare your notes later.
Remember, more expensive doesn't mean better; it just means different—or maybe the same.
And while it's fun to have a board that looks cool, you may want to consider that a keyboard's primarily a tool—and if you're using it right, you won't be looking at when you use it, any more than you'd look at your feet when you ride a bike.
And please don't just "type" on disconnected keyboards. That's like choosing a car by sitting in it in the dealer's showroom rather than taking it out for drive. The best keyboard for you is the one you enjoy typing on the most. Just pressing keys, without seeing the characters you produce, isn't typing; it's just pressing buttons. It's a subtle difference, it matters. Good luck!
