IMO, the best switch for typing and gaming (fps) if both have equal priority is MX Brown.
MX ErgoClear (Clear switch with lighter spring) is better for typing, but a little less effecitve for fps gaming since the bump is quite pronounced and pushes the slider up / down so it's hard to keep it close to the actuation point, it tends to force you to press / release fully past the bump. The bump on browns is smaller and starts a little lower, so you tend to not move the slider as much when trying to keep it close to the actuation point. Reds don't have the bump at all, so you can "hover" fairly easily if you are very used to where the actuation point is on them (but I don't like them for typing, I tend to require some form of tactile feedback to type fast and accurately). Blues and Greens have a reset point which is above the actuation point, so you have to release the switch almost to the top if you want to press it again. It's fine for most situations and great for typing, but if you want the fastest response on your movement keys it can get in the way a bit. They feel nice for typing, though, since the tactility is a little different to Browns / Clears and the extra auditory feedback (click) helps you register when the key has actuated.
I game on Browns and ErgoClears and prefer the ErgoClears when I'm not feeling competitive. The tactile feedback is very satisfying. If I really feel the need to be at my best, though, I use the Browns. In your situation I would get a Poker 2 with Browns. If it aint broke......
