Based on my understanding, at the time of the first Asterisk server was developed, there was no GUI for the server, the sip settings were all placed in sip.conf. The dialplan is placed in extensions.conf. There is no such file users.conf.

After the introduction of AsteriskNOW, a GUI for Asterisk server, the file users.conf is introduced. The general or register settings are placed in sip.conf. Individual sip client settings are placed in users.conf. The settings for dialplan is remained the same, i.e., extensions.conf.

Different user's preference may have different choice of placing individual sip settings. Both ways are acceptable in Asterisk server.
