Add the -s (-stats) option to the ip command.
Example: a can be used as a shortcut of addr show.
ip -s a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
<snip>
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

One can really forget ifconfig. For example, ifconfig do not output the
permanent mac addresses of the wifi interfaces.
Example: see the permaddr below:
ifconfig -a
<snip>
wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether e2:71:46:a6:ee:81 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
ip a
<snip>
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether e2:71:46:a6:ee:81 brd ff:ff:ff:ff:ff:ff permaddr 00:24:d7:0f:d4:2c
