Keyboard?

As everybody's talking about mice and which one's best I always wondered which keyboard is best or good, because right now I'm looking for a good keyboard. My old one can't recognize many keys at the same time, e.g. when I press the keys for moving forward, left and the scoreboard I can't jump. In addition the buttons on my keyboard are very hard to press so and I noticed the same behaviour on some other keyboards (not all I already owned) and no want to ask you which keyboard do you prefer/especially like? (buttons easy to press, button layout, design of the keyboard, maybe lighting on the buttons, etc.)
Thanks for information!
Greetings!
