When u setup a DHCP address reservation in Router you should leave the Pi set to DHCP. When it boots and asks Router for an IP address the Router will look in its DHCP reservation table for a matching MAC address and then assign the corresponding IP address to the Pi.
If you just set a static IP address on the Pi and don't also exclude it on the Router by limiting the range of DHCP addresses the Router can assign there is a risk that the Router will assign that address to another client and then you end up with an IP address conflict on the network.
