Keyboard advice?

Simple and straightforward like it says. My old keyboard is starting to go out. Multiple keys aren't registering and I've been working around it but I'm about over that.

Any advice or personal experiences with keyboards you would be willing to offer?

Also what about the switches? Red, blue, brown?

Finally if you're wondering I literally only play this game and do some work on the computer.

My friend is recommending blue switches. He uses his for work a lot more than I do however he said it's a good all around switch.

Thanks yall!
