Cat7

CAT 7 cable is considered the most durable ethernet cable. Has a longer lifespan than CAT 5 and CAT 6 and is the best choice for wiring with the future in mind.

Cat6
Cat6 is the choice for future-proofing in-wall home networks, since there are plans in place to use Cat6 to replace HDMI as an A/V standard in the near future. Cat6 is also better at minimizing interference.

Cat5e
Cat5e is the current standard for any modern residential network.

Cat5
This cable is commonly connected using punch-down blocks and modular connectors. Most category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection.wikipedia
