It depends on whether you often need to reach across the keyboard middle. If you need to press keys on the left half with your right hand or the other way around, it will be uncomfortable. Specifically for shooters I've found it pretty great though. I usually only need the left half of the keyboard anyway, since the right hand almost exclusively uses the mouse. Having a split keyboard means I can push the right half back and have more space for the mouse. I am, however, also the kind of person that rebinds 80% of hotkeys in games to what I like, so I will always go to the trouble of binding every single important action to a key on the left half of the keyboard in shooters. So take that with a grain of salt.
