avahi-autoipd: may be used on networks which lack a DHCP server. That
               likely does not apply to you. Most users will not miss
               it. What occasional issues have you had with it?

avahi-utils: if a user does not want to interact with the Avahi daemon,
             this package is not needed. What occasional issues have
             you had with it?

avahi-daemon: allows applications to publish and resolve mDNS/DNS-SD
              records. Most users appreciate and make use of this 
              facility. What occasional issues have you had with it?

These "occasional issues" you have had quite likely do not relate to a
cause originating with any of the packages above.
