I don't think there is a mechanical keyboard to rule it all due to personal preference.
I like blue for typing but settled with black for occasional gaming. (you don't really want that "click" when playing games).
Electrostatic-based keyboards like Topre RF or PFU HH are nice but I personally don't see the added benefit given the substantially higher price tag than a good Filco/DAS/WASD based on Cherry switches of one's choice. And the fact that I'm on a Mac makes keyboard shopping even worse.
