Help me choose a keyboard

Depends on what are you looking for in a keyboard.

Edited the title OP just to add some information.

It depends what budget do you have for it - you might choose membrane keyboard, or mecha-membrane or mechanical. If mechanical - there are few types of mechanical switches (tactile "clicky", tactile silent, lineal silent).

It's very simple if you want advaice from community just write few things :P What you will be using keybord for, if it's game what kind of games, if you want chroma or you just dont care and the price limit you have :)
