What is a Good HDMI Switcher / Selector to Buy?

[Vargus]

I was after a HDMI Switcher / Selector, preferably one that contributes the least amount of lag if any, powered and at least 4 ports.

I found these, but don't know if they are any good...

The two outputs will come in handy for streaming / capture.

and I also found this one...

Happy to buy elsewhere and online if better and / or cheaper.

Any recommendations?
