They are not equivalent.  Yours leaves extra whitespace.

wooledg:~$ ip -o link | cut -d : -f 2 | hd
00000000  20 6c 6f 0a 20 65 74 68  30 0a                    | lo. eth0.|
0000000a
wooledg:~$ ip -o link | awk -F": " '{print $2}' | hd
00000000  6c 6f 0a 65 74 68 30 0a                           |lo.eth0.|
00000008

So, to use the output of yours, an additional step would be needed
(whitespace trimming).
