There are two big reasons to use Wireshark:
its huge number of protocol "dissectors" that show you what the bytes mean, and
its filtering language.
For example, if I want to filter Wireshark’s output such that I only see packets from my computer to UDP port 67 or 68, I can use a display filter like:
ip.src == 126.96.36.199 and (udp.port == 67 or udp.port == 68)
