I prefer a matrix: A 4x2 one will allow you to choose which of 4 devices (for me: PC/PS4/Wii U/PS3) to route to my capture card (output A) and TV (output B) without unplugging. I got this one:

Zero delay.
For HDCP I got a little thingy from AliExpress that removes it (for the PS3 or when I want to capture my phone's HDMI Out).
Only problem with cheap matrix switches is that they don't hold the EDID handshake. So every time you switch them, the devices attached see the monitor get unplugged, then plugged in again instead of just transferred smoothly in the background. Especially a problem if one of your inputs is your GPU for whatever reason... on a multi-monitor setup, it tends to scramble your desktop pretty good when that happens. Even when you're changing the *other* output, and not the one to the monitor, usually both get refreshed.
I ended up fixing mine by grabbing a Gefen HDMI Detective. Not cheap at around $70 apiece, but super worth it. Especially as most matrix switches with proper EDID-hold tend to be in the four digit price ranges. :b
Only problem now is that sometimes it confuses attached devices, that don't handle hot-swapped displays well. Easy enough to switch away and back again (or off and on again), but still a little annoying.
That seems pretty useful....
Oh, it is. And a steal at $20, not to have to screw with component cables and ghosting and other problems associated with a dip into analog.
